Steps to reproduce

The issue is that I click and drag the right side of the MS Edge browser or the upper right corner or lower left corner and the new space that I expand into does not show MS Edge browser content. It appears as if the inner content is transparent. I can see the border of the window expand, but everything inside the expanded border (including the top window bar) is invisible. The area previously containing content continues to show content and it changes its layout as if it were expanding into the transparent region. I “know” that the content has moved because if I click the transparent spot where the window close “X” should be after the window resize, I can see the window close.

This is a repeat of Issue #14245708 marked as “not reproducible” which is bogus. I can make this happen any time you want to see it. Other users are also experiencing the issue and commenting under issue #14245708 so it shouldn’t be ignored. I am a developer so I understand that it can be difficult to reproduce an issue, so perhaps you need to investigate on machines where you see it happening. I would be happy to remote desktop to look into the issue. I can run test code to log more information. I am on the latest updates for Windows 10.

        Edge and edge based aps (Calculator, settings..) window resizing problem



        I am using multiple monitor settings with primary 4k monitor and multiple 1920x1200 monitors. The Edge and edge based aps (Calculator, Settings - is it edge based???) has resizing issue. When enlarging the edge window the enlarged area is not rendered (it shows whatever is under the window in the enlarged area) or the whole area becomes grayed out and none of the windows controls are working. Similar problem happens mowing the window from smaller resolution monitor to the high 4k one. This issue can be observed only after some time of usage. Right after reboot it is usually Ok, but after some time it starts showing and remains until full reboot. I have observed on multiple versions of windows 10 and multiple computer set ups, typically with high resolution 4k monitor. It makes the Edge and other aps unusable once it happens.

  • I see that Paint 3D from Microsoft also has this issue with the same transparent interior behavior. This may be a shared library between the two applications or an OS level issue.

  • Same issue. See attachment.

    When window is resized to be larger than its initial size, the new area is not rendered and shows as transparent. This happens with a number of “native” MS Apps: Edge, Mail, Calendar, Windows Settings.

    Hardware: Lenovo Thinkpad T430 with Intel graphics
    OS: Windows 10 Pro, Version 1709, OS Build 16299.371

  • Microsoft Edge Team

    Changed Assigned To to “James M.”

    Changed Status

  • Hello,

    Thank you for providing this information about the issue. We are presently tracking this issue as a duplicate of an existing internal bug report. We look forward to additional feedback you may have on how we can improve Microsoft Edge.

    Best Wishes,
    The MS Edge Team

  • Same issue as described above. Seems to affect Edge and Mail only. Does not affect older Microsoft applications (Office 2007 or MS Money for example) or Google Chrome browser - so I am using Chrome for browsing now.

  • This has been a issue for years now. Please resolve asap. It makes Edge unusable, especially on high DPI displays.

  • I had this issues, then fixed it (don’t remember how) and it came back when I did the latest updated.

  • The last Windows 10 update to v. 1803 brought the same problem to my Lenovo IdeaPad 110-15isk with Intel HD Graphics 510 integrated display adapter (video cared) following the last hardware upgrade by Lenovo, incl. BIOS to v. 1TCN24WWV2.05; seems like a problem of Edge with the latest and stable graphic driver v. of 3/9/2017, so MS’s fault.

  • I meant “video card” above. The problem is bothersome when Edge is opened in the full screen window (mode) with the “double” square, as the 2nd icon from the right in the upper strip of the window, then switched to the adjustable window mode with the “single” square icon, which causes the window to dramatically shrink, and subsequently enlarged. A temporary solution is to display Edge only in the adjustable window mode in the max. window size. Only then reduce the window size. Before closing, expand the window size back to the max. and only then close the window in the adjustable window mode with the “single” square icon. To get the window open in a big size after switching from the full screen window (mode) with the “double” square my require to switch, close Edge, and open again several times, as after the switching and closing, Edge may open in the full screen mode again a few times despite Edge was closed in the adjustable window mode.

    It is definitely MS fault and has to do with showing the image of Edge’s content in the rectangle of its window by Windows 10 (multitask filling up appropriate areas of the full screen of the device/computer with the content of particular programs), i.e. filling up the Edge expanded window rectangle by Windows 10 on the front, visible layer with the content previously covered on a lower, only partially visible layer. In other words, expanding transparence of the front layer to match the bigger Edge window and to show that size of the full screen of Edge from beneath, as the rectangle of Edge window dictates. Quite a shameful rookie mistake in display layer management by Windows 10.

  • BAD NEWS: After the Windows’ power option turns off the screen, the content/image of the Edge screen window disappears leaving a blank window’s frame and Edge is frozen. Then, Edge has to be turned off using Task Manager. Power issues could be not Windows 10 related, but computer’s BIOS… recently upgraded. What a drag.

  • EASIER TEMP SOLUTION (not always working): Switch from the full screen window (mode) with the “double” square, as the 2nd icon from the right in the upper strip of the window, to the adjustable window mode with the “single” square icon, resize the window, right-click on the Edge icon, and select/open "New window", which should be the same size, but fully filled in with the Edge image.

  • IT IS WINDOWS 10’s PROBLEM: I started keeping Edge in a window almost the size of the screen and closing it only in Task Manager. Subsequently, other Windows 10’s windows, e.g. of Settings, increased to the same size. When RAM/memory use is significant, e.g. 80+ %, the content of Edge disappears when the screen gets turned off by the power management. All that indicates the Windows 10’s RAM/memory management problems signified by Edge, as a biggest app user. What a shame.

  • I’m getting this with Edge and the latest version of Skype

  • Hi Dave,
    A recent Windows 10 automatic small update fixed the problem, except the situation when a lot of RAM/memory is used in conjunction with not so good, but free GIMP 2, which often malfunctions especially with large files/images. Then that problem with Edge appears. Usually, closing GIMP 2 and Edge does fix the problem. Otherwise, restarting Windows 10 do. Your trigger might be Skype, as involving graphics as well. Simply, Windows 10 might have difficulty in handling 2 graphics demanding programs at the same time especially when the use of RAM/memory exceeds… 80-85 %. So, the RAM use needs to be monitored, e.g. by turning on the Task Manager.

  • My wife is having the same issue of the transparent screen when trying to expand Microsoft Edge. Fortunately… I use Google Chrome and POOF! No issues!!! Thanks Microsoft for proving me right!

    But… if there is a fix for Microsoft Edge… my wife will thank you!

  • Hi Michael P.,
    It is not Edge, but Windows 10 when run short of operational memory (RAM) at ~80-85 % use, which might be caused by not so good and memory hungry app, i.e. graphics intensive, as in my case GIMP-2.08. After upgrading to better GIMP-2.10 the problem almost disappeared except when I open many windows in GIMP.
    Try to prevent all unnecessary apps that load automatically at the start of the computer in ‘Task Manager’ > ‘Startup’ by switching their status to 'Disabled’. They will still load when needed by being invoked by clicking on their icons or by other apps.
    Also, do upgrade all apps to newest versions where available esp. graphic intensive, i.e. not like MS Office, but for manipulation of images and playing video or teleconferencing, e.g. for Skype.
    Good luck.

  • After 35 years of using Windows I have learned when to give up on Microsoft fixing anything. I am fully up-to-date with windows updates and have 32gb of available ram using a GTX1080 display with 5560 horizonal and 1920 vertical pixels of display resolution and still have an Edge browser that does not know how to resize a window. Yes moving it full screen and then closing it will get it back to full screen without a transparency issue the next time you open, but pop-up windows still have the same problem. And if you make it smaller and forget and close it you are right back where you started. Just use Chrome and remember the team you are talking to is clueless.

  • Hello William Z.,
    The 1st Windows marked “3.1” was released in 1992, so only up to 26 yrs ago and not 35. Edge is not the only app with this problem. If it were, you might be right. Thus, it is rather Windows 10 problem and, likely, only with some graphics cards/drivers or memory paging/managing swap file, etc. I am not defending MS and agree 100 % with your opinion, but just trying to be constructive in case someone needs Edge for whatever reason.

  • thanks Eugene. I started with the Altair 8800 in the early 70’s and moved to Kendall’s CP/M in the late 70’s and eventually evolved to DOS. Pretty sure I started using windows around 1985 when it was only a shell for MS-DOS. I know because I was writing a separate product then that used its own windows-like shell in DOS. Windows V2 was a few years later. Then V3 in the 90’s. So maybe it was closer to 33 years to be more exact. Point was only to illustrate I am not a Newbe, had a chance to stand on stage with Bill Gates once (no pies that day), and still know enough retired MS people that I should call one of them to see if they even give a flip. I only see the problem with EDGE/Explorer. But I have many different Windows computers without the issue. Only my high-end desktop with a ton of ram and the GTX1080. I am one of those old EE/CS geeks and can image many reasons for the issue. I have toyed with the idea of removing some RAM just to see if the problem went away. What other Windows Apps are experiencing the transparency expansion issue? Mostly just a challenge now to see if it ever gets addressed as Chrome gets the job done just fine. I am retired but still have to use Explorer to test if I am getting web pages I may write for an IOT hobby project compatible with the old Explorer. Now with an Edge face lift.

  • William,
    Dave C. reported Skype above ‎on Jul‎ ‎20‎, ‎2018. I had the same with Windows “Settings” window. All of that appeared for the 1st time after the last Windows upgrade coinciding with automatic BIOS upgrade by Lenovo related to the last big security issue.
    I think the total amount of RAM is secondary to the way how the screen image fillings are managed probably within the first 4 GB of RAM. Please, notice that the outline of enlarged Edge window gets bigger, and only it is not filled in properly. That seems to be the issue of cropping each app’s full image to the visible part fitting its window not processed by the app, but rather by Windows. More details above on June 3.
    It is possible that Windows 10 treats MS apps differently than foreign. Maybe they have a special mode, which is supposed to work faster, but still clueless how to make it work well. Who knows. They have the Windows monopoly and do not care too much.

  • Thanks,

    I can confirm settings and skype both share the windows issues. Sorry I was remiss in reading the entire thread. Given only MS products are suffering I suspect you are correct that an internal short-cut in windows, probably unavailable to others, is the root of their issue, just above the root of not really being that concerned. Or they share a common library of code that has the problem and it is just propagating through the Microsoft Family like a bad virus.

  • One famous quote from a former Microsoft Developer… “If it boots it ships. QA is the customers responsibility. Ours is to listen and then carefully pick issues that actually cost us money to try and repair.”

  • Well I just installed Visual Studio 2017 and now the problem is gone.

    No explanation but I won’t complain.

  • William,
    Are you saying that just going to https://visualstudio.microsoft.com/downloads/, clicking on the ‘Free download’ button under "Community", and installing the Visual Studio 2017 software did solve the problem? If yes, I am curious, if uninstalling VS’17 leaves its small part/library, which fixes the issue as well.

  • Yes that is exactly what I did and the problem went away. New/different DLL maybe? Might explain why MS developers can’t duplicate the issue. Suspect most of them have Visual Studio installed by default. Thought it might be back this morning but everything is still working fine now.

  • Changed Status

  • I have had visual studio installed this whole time and always with the most current version available. It didn’t solve the problem until possible this latest release. The dot net runtimes get updates with visual studio installs so it is likely this that could be the fix.

  • Visual Studio 2017 was installed when I had the problem. Issue went away for me after installing a new graphics driver from nvidia

  • Curious… I tried all the latest Video drivers from Nvidia and countless reboots with no change. The only change that worked was the VS 2017 install w/reboot. I guess it is at least one more thing to try for someone still suffering from the problem.

  • William,
    MS “developers” could not replicate an apple falling on Newton’s head nor could find a hay stock on the top of a needle, etc., as they are waiting for someone to shove the solution… "into them".
    Since the outline of the window is updated/expands and its image filling not, it looks like a problem originating not further than the graphics card/GPU, as GPU processes vectors and raster/fillers separately. Since my GPU was OK before the last driver upgrade, it must be something related to the driver. Since the driver processes some apps correctly, it must be Windows 10 GUI’s (https://en.wikipedia.org/wiki/Graphical_user_interface#/media/File:Linux_kernel_INPUT_OUPUT_evdev_gem_USB_framebuffer.svg) fault in the raster channel serving MS’s apps, e.g. no instruction to refresh by a screwed up variable, or just Windows’s handling memory for GUI (also, e.g. one variable).
    How difficult it would be to check and replicate GUI for… a normal developer?! I would start from buying a laptop, like mine (Lenovo IdeaPad 110-15isk) for… $240 (www.newegg.com/Product/Product.aspx?Item=9SIADUJ7A96829), removed 2 GB of RAM (I have only 4 GB), and… voilà, you can replicate everything. I do not think it would be a rocket science even for MS.

  • We need to establish, if it happens with add on GPU’s with their own memory or with integrated GPU’s sharing RAM with CPU. Mine is integrated Intel HD Graphics 510. Michael A. has Lenovo Thinkpad T430 with Intel graphics too. But you said you have nVidia. Is it integrated too?

  • I have both Intel HD 530 embedded but not used and nVidia GTX 1080. Both with all of the latest drivers. Trick for me now will be to try and “back up” and recreate the problem. Maybe this weekend if I have nothing else to do. I suspect if the Intel driver is loaded, even if not used, it could have still caused some issues.

  • Microsoft Edge Team

    Changed Assigned To to “Steven K.”

  • Hello all,

    Appreciate all the responses with workarounds and potential sources of this issue.  It sounds like there may be multiple reasons that cause this issue to appear.  I will update the internal ticket.

    Based on the last couple comments, I would like to know what amount of memory and what graphics card each system that still has the issue is using.


  • William, nVidia GTX 1080 is a big add-on piece of hardware not using - I think - system’s RAM at all.
    Steven, I would also ask for all apps severely taxing GUI. In addition to GIMP-2.10, which eliminated problems with 2.08, I have nasty software for MagicJack, which often requires restarting, because does not popups when it should, gets deaf, or else.
    Just a moment ago, my Edge video of DW Euromaxx lost sound. Refreshing the page did not work. I had to close the Edge’s window and restart the DW page. Afterwards, after reloading Edge, my top site icons do not display proper images, but only generic, on the initial Edge page, but they will come back with… time.
    What a mess?! And you want to compete against Google… ha, ha, with what?!

  • Correct, the 1080 is a complete GPU on its own card. Your slow icons sound like icon cache problems. You can tweak that some… https://www.thewindowsclub.com/increase-icon-cache-size-in-windows

  • They are not system icons, but 8 big rectangles - almost squares.
    But coming back to the improvement by upgrading GIMP from 2.08 to 2.10, it just cut memory leakage. In case of your nVidia GTX we can conclude that it does not receive the instruction to resize, because, if it were, it would do as independent.
    So, what those processes have in common or, if nothing, is there a preceding commonality. They suggest the problem may take place in Windows 10 before GPU is engaged. So, where? The common place for both would be disturbance in receiving by Windows 10 instruction from the input device. In my case it would be added cheap iMicro MO-159U optical mouse using standard MS HID-compliant mouse driver. Hence, the MS mouse driver bad esp. when Windows is choking under memory leakage or else?
    I would start from there. Namely, where the instruction from the input device separates into vector resizing of the window outline/frame, which is working, and into resizing the raster, which is not working and likely does not even reach the graphics card, which updates the raster, but does not change its size to fill in the outline properly.
    So, William, what kind of a crappy mouse do you use?

  • I use a pretty expensive Logitech Trackball. Not really crappy. Have not done any logitech driver updates ever that I can remember. I always thought it had something to do with the SWP_NOREDRAW flag of a SetWindowPos call being overwritten someplace. That is what I would do to actually Try to write code that exhibited the strange behavior. Set that flag resizing the window, then just forget to do the UpdateWindow part. Or something like that. Maybe an untrapped error causes code to get skipped?

  • I was trying to be humorous, as people with nVidia GTX do not use $5 anything… maybe except cables. Anyway, we provided Steven K. and the rest of the MS Edge Team (see above) with something they could start from… maybe… if our above opinions on them were… too harsh.
    I do not think it is SWP_NOREDRAW, as the error pertains only to the size of the raster, and not its position or content, as its refreshing is not impaired. That should dramatically narrow the area of error location.

  • William,
    The problem can be recreated at least on my laptop with 4 GB of RAM used 88 % in the following way. Do install free GIMP. Do open Edge with at least 7 tabs, in each of which do some heavy browsing/editing back and forth many times, e.g. do open people’s review history in Amazon.com and do scroll down to see hundreds of reviews in each tab. The objective is to have as much memory used per each tab as possible, preferably hundreds of MB by each. You can check RAM use in Task Manager.
    Then open several big images (*.jpg) in GIMP. Do zoom in and out in each. Then try to resize those GIMP’s windows. At certain moment GIMP refuses a window to be resized. At the same time Edge shows the same our problem and other apps as well.
    Good luck and let know.

  • And then switching in Edge between full screen and smaller window then resizing in any tab chokes Edge. Its windows turn gray, it becomes suspended, and requires forcible closing in Task Manager. When restarted the problem persists below 80 % of RAM use, but not when window is not switched from the full size. Still crappy.

  • And I also cannot delete in Windows/File Explorer those *.jpg file used by GIPM. So, Windows 10 is failing throughout. Windows Explorer and file management - in general - has been historically week/plagued by deficiencies in MS Windows. Basically, it is data management. Maybe, memory management is at the root of all of those failures?

  • …or the mechanism of suspending the apps or an inability to reverse the suspension due to its poor/buggy programming?

  • I have 32GB of available RAM. It is going to be difficult for me to use that up to 80% just loading programs. I think there may be a tool someplace that just allocates a bunch of memory for no reason just for system testing. MS has never been good at memory management. But I remember studying the concepts in Computer Science classes and it can be challenging. Years ago the OS Malloc was failing pretty badly, not returning the correct amount of available ram. We found that if we tried to first allocate more than could ever be available, that it would accurately fail, saying no you can’t have that much as N is all that is available. Which was the accurate number. Then we would go ask for that much in Malloc and all was good. I have heard that much of Windows code is a bowl of spaghetti. So many pieces and teams. It has just been around too long to not be. It is all about keeping up now. Getting ahead stopped being an option years ago. I tend to use Adobe products for images but will load up GIMP and see what it does.

  • William,
    But maybe you can remove some RAM from the rig, right? Maybe, you can try on a smaller computer, if you had one?
    Now, I am not sure that it was GIMP, because as long as you open Edge in the full window mode, GIMP works fine. Once you reduce Edge’s window and stretch/shrink a few times, only then GIMP starts failing, but I can not even open next image, because Windows/File Explorer does not work as well. Once Edge is forcibly close, both Explorer and GIMP come back to life. I think, maybe GIMP only accelerates the problem.
    Ergo, Windows 10 is screwed up pretty well.
    Now, MS could definitely recreate the problem after spending $240, as advised above. But maybe, MS would be not interested, as unveiling their own mistakes might potentially challenge their… bonuses?! Maybe, they are not interested to provide good products at all?!

  • After a few hours I was able to delete files. Then I shrunk Edge from full size and back and it got stuck in the full size mode in shrunk window without seeing its right part. None of the other windows on the right were accessible. So, I assumed that all are covered by invisible right side of the Edge window. So, I clicked in the upper right corner of the screen, where the closing Edge window “x” was supposed to be and it closed Edge despite there was nothing visible, but just the desktop background. That explains why I could not delete files in Windows/File Explorer before. Though Explorer was visible, but it was covered by invisible part of full screen Edge only partially visible only in its shrunk window. MS incompetence is so ridiculously… funny. They managed to create… ghosts.

  • Here is a curiosity. All I did was Install GIMP, open and play with it some (loaded 15 large images at the same time) and the problem with windows going transparent on windows re-size beyond the size when last closed, returned. Rebooted. No change, still broken. Uninstalled GIMP. No change, still broken. Rebooted after the uninstall. Problem gone again! I’ll sleep on it and try this experiment again tomorrow. Maybe just install GIMP and not load an image to see if just installing brings back the problem or if loading images made a difference. Hoping for something repeatable.

  • I did the exact same GIMP install this morning. Loaded the same JPG files. No problem with Windows this time. The Error certainly showed up and went away yesterday, but I can’t seem to repeat it. Trying to remember what else I had open yesterday during the GIMP install. I loaded up a directory of several 100 JPG and used RAM to 22GB and it just started caching the remainder. Nothing I do now seems to re-create the issue. I’ll wait a few days with the system running and then try again to see if something happens over time that enables a GIMP install to trigger the problem again.

  • William,
    I think the problem requires using GIPM when Edge in quite loaded and Windows 10 is running for quite a while. I think, that might have been the difference between your yesterday’s and today’s attempts. Only after Edge occupies a lot of RAM, using GIMP to resize big drawings eventually freezes one GIMP’s window.
    Nevertheless, MS cannot claim anymore that that the issue cannot be recreated, because that is the way to do. So, we did the intellectual part of the issue (with resizing of window raster), and the MS grinds/swots could do the rest… if they are not too dumb.
    I have ability to program only in (Auto)LISP). In the early 1990s, Logitech had a mouse with more buttons and a driver overlay software to assign/program buttons for AutoCAD. Good God, that piece of shit was causing galactic problems resulting in constant freezing of the screen and hanging up of the computer. I think, this issue could originate in GUI as far as just after Windows 10 receives input from a pointing device.

  • Remember, in addition to GIMP’s, you need to resize also Edge window from full size to partial and to stretch partial one, go to GIPM, and than back to Edge several times.

  • Maybe it is the failed transparency feature of… the Vista, which somehow snuck into the Win 10’s GUI?

  • Microsoft Edge Team

    Changed Steps to Reproduce

  • Setting scaling back to 100% is what fixed the issue for me. Maybe this will provide MS a clue for troubleshooting, and others a tip for a temp workaround.

  • Hi Katya,
    We already new that it helps… sometimes… at the beginning, but not in heavily utilized systems, where the problem is persistent, leads to freezes, and ultimately requires restarting. I often need to work simultaneously with 2 windows next to each other, incl. GIMP, and temp. workarounds are useless for 2 reasons. First, does “temp” mean many months, years or - actually - next several generations of Windows for MS? Second, as this issue is older than March when it was reported here 5 mo ago, dismissed due to apparent MS’s inability to recreate, reopened when recreated by us - users, so do you now attempt to “swept it under the rug” to fake MS’s concern and attention, to pretend providing “temp workaround” when it is neither? Do you think, how stupid are we?

  • would love for this to be fixed. this completely ruins my workflow multiple times a day, forcing me to reboot.

    I don’t have gimp installed and I’m using a Microsoft surface pro 3 on 1709.

  • update:
    sometimes if you minimize and restore a window that is affected, it will display blank. I tried to fix this by killing random processes for fun.

    nothing that I killed from user-scope helped EXCEPT… killing “ApplicationFrameHost.exe” closed all UWP apps affected. when I reopened them, they displayed content, but they still have the issue of displaying nothing when expanding the window.

    will try killing processes that require admin rights next.

  • only killing dwm.exe had any results… pretty much the same as killingapplicationframehost.exe.

  • Hi Robert,
    It would be useful, if you described in detail how to recreate the problem on your computer at any time incl. all loaded/started/active apps. In other words, what you need to do to have the problem to appear incl. all present apps.

  • What I love about this conversation is seeing that MS is actually paying attention. Don’t count on my memory for anything, however I have been programming and (lately) tutoring since 1969 and am still a "newbie".

    The transparent expanded borders and the occasional blank Edge window have been happening on and off for probably over a year, for no apparent reason, that I can recall. - on my previous old HP 8G RAM machine, which croaked about a week ago, and on my new HP 12G beauty.

    Best Buy successfully transferred all of my data which did not include purchased or system software, so the new Windows and Edge are pristine and clean. Edge is still screwed up.

  • Based on the comments of William and Eugene above, I also installed Microsoft Visual Studio 2017 Community edition.

    I can confirm that installation of MS Visual Studio 2017 fixes the problem. This means I no longer experience the problem.

    Additional observations:

    1. This is Windows 10 Pro latest update, 1803 build 17134.228. Prior to installing MS Visual Studio 2017 the problem still persisted.
    2. The problem starts after the laptop has come back from power save.
    3. My company have several other laptops with similar configuration that never experienced the problem. The problem must be related to a specific library or similar that was installed on this laptop.
  • I have since discovered that this is happening with other built-in software such as the Windows Settings box and Sticky Notes, perhaps more. This is on my new 12G RAM HP machine bought a week ago at Best Buy. Sticky Notes remembers its new dimensions and reopens correctly; Edge does not.

  • Correction: now Edge does remember, usually, but sometimes reopens full screen and then looses my preferred dimensions, reverting to some kind of default.

  • @Eugene I’m really not sure what causes it. It may be after my computer goes inactive & kicks me out to the lock screen, but that also doesn’t seem consistent. usually happens at least once a day at work.

    could have something to do with multiple monitors as well. I’m using the new surface dock with two monitors.

  • @Michael, will the problem persist after you uninstall Microsoft Visual Studio? Could you check it?

  • My laptop has always been fine. This weekend I tried adding multiple monitors to the laptop and it started acting differently. It worked but when I extended a window size, instead of filling in with the new contents as I expanded like it usually does, it drew an empty window in the expanded space like it was not going to work, then when I released the mouse button it properly filled it in. My suspicion is that had I been able to stress it just a bit more for memory, that last fill-in after the mouse button release would not have worked. But personally I think we are all wasting our time on this. Microsoft does not care about this issue. It is not revenue related, affects only a small number of people, and often resolves itself in some cases. If they did, someone from MS would have posted a question that helped direct the search. Like if you swap out this DLL does it make a difference, etc. Anything to show they were actually in search of a solution. That is not happening. The VS update fixed it on my computer and I have not been able to reproduce it on my desktop. Might try again to break it on my laptop. The refresh as you change size vs. refresh after you change size issue got me curious again.

  • Or it is an issue of the badly written kernel and GUI and they have no clue how to fix it. I was not closing Edge for 3 days, the laptop’s screen went black around a security maintenance, which often disturbs opened apps, and I had to reboot, but it took several minutes of pressing on the red power button to implement. I also thing that we are wasting time, but at least we did our part.

  • I tried to break it again yesterday. I opened tons of windows, apps, resized, etc. It kept working. But then I went to an app that has a built-in editor that does not wrap text, and purposely pasted a Very long line. It broke the editor as I might have expected. But it also broke windows again. Now even without the editor the problem is back. I have not rebooted, trying to see if anything restores functionality but no luck. So I will try a reboot sometime today and see how bad this problem really can be. Now even Facebook is dragging an empty window. I think your “No Clue” is probably an accurate prediction.

  • When I was programming in AutoLISP, I was never leaving loose ends and always placing an error message with a unique number to be displayed when a limit was exceeded. That way I always new when the error occurred. I do not think that those morons program safely. The problem could be caused by an old data buffer left too small and they have no clue where it is. Well, c’est la vie.

  • Here is something new I think… https://youtu.be/nMnkYrgDwyk

    Edge is good on the left monitor but goes partially transparent when I drag it to the larger center monitor. Hopefully this will give the programmers NOT looking at this post another clue.

  • Actually it looks like it is the same issue where the resolution is changing, but this is NOT me dragging the window to a larger size, but it actually resizing itself and still failing.

  • @William, pasting a very long line in a primitive text editor was a brilliant idea, as it simply tested its data buffer.
    Visible app windows, which lie under a transparent part of not filled by raster front window, are not accessible, but invisible right corner buttons of front window, when in full size, located in part not filled by raster, are working and are closing faulty front window, so GUI is informed of new size, window frame moves (expands and contracts), but its filling in raster is not expanding, though it is contracting with contracting frame, which is another clue, as to the location of the error(s). I thing that freezing of any (bad) app window spreads on (confuses) GUI, Edge, etc.
    Recently, I have not noticed repetition of the problem even when RAM was used 90 % by Edge and GIMP, so I gather that they (MS) are actually working on the problem and corrected something through the automatic update… I hope.

  • In other words, only that part of GUI, which sends info to graphics card to expanded window raster, is not working and gets corrupted by frozen, not expanding anymore windows of variety of apps. It must be in the part of GUI, which joggles raster data, and data from one frozen window must stop calculation of raster in other windows by being null or constant or else, God knows how it is handled.

  • I found the solution in an article about something similar in the “Windows Secrets” newsletter:

    Five Time-Saving Windows 10 Productivity Tweaks 2018-09-11
    Top Story: Michael Lasky
    Turn Off Windows Visual Effects, Turn On CPU Speed

    1. Open File Explorer and from the left column, right-click This PC.
    2. From the drop-down menu, click Properties.
    3. Click Advanced system settings in the left column.
    4. Now click the Settings box under Performance.
    5. The Visual Effects tab reveals all the visual features Windows loads by default.

    Click “Adjust for best performance” & OK.

    I have had no problems since doing the above.

  • Van’s solution worked for me. Thank you!

    Because fonts/text will look on the screen like crap, I would suggest the following continuation/modification of the Van B’s solution:

    1.         Click “Adjust for best performance” (as suggested).
    2.         Click "Custom".
    3.         Mark only "Smooth edges of screen fonts".
    4.       Click the "Apply" and "OK" buttons and exit.
  • Adding to the above, I also found that setting to best performance looked really bad. I was able to switch it back to best appearance, then just deselect “Show window contents while dragging” and everything looks good and works correctly. It appears the problem is just that one setting.

  • @Steve K, it looks like you have found the culprit, i.e. the screwed up function "Show window contents while dragging", consistent with all we had observed. I would advise to disable all visual effects, except "Smooth edges of screen fonts", for all whose computers choke or are slow, e.g. for slow processors or small amount of RAM.

  • After installing MS Visual Studio 2017 Community Edition the problem had disappeared for a while. However, yesterday Cumulative Update KB4457128 arrived and the problem was back. Windows no longer rendering into resized space.

    I uninstalled MS Visual Studio 2017. It did not change the problem.

    Then I disabled “Show window contents while dragging” as mentioned above. This fixed the problem immediately. No restart required.

  • Also, the function “Show thumbnails instead of icons” is very useful, so I would keep it on in addition to “Smooth edges of screen fonts” in the min. set of visual effects of just 2.

  • After the recent cumulative update the issue had spread to Windows Defender security center, causing it to be even slightly less usable than Edge as on my system it opens in a very narrow window and does not remember the adjusted window position/size between launches. Turning off “show window contents while dragging” fixes the issue, but it is oddish to keep toggling that to just be able to use a built-in thing.

  • This has now reached the point where Edge has become unusable. Luckily there is Firefox and Chrome.

    Some this reported bug manifests when you try to horizontally resize, sometime when you resize vertically and sometimes when resizing both at the same time, e.g. using the lower right corner of the Edge window.

    Other bugs in Edge:

    • Process doesn’t finish when windows is closed (not always but increasingly often). Then the only option is to kill the process using Task Manager.
    • Opening a link in a window results in that new window to be maximized. The new window also shows the resizing problem.
    • Observable speed is noticeable slower on Edge than Chrome or FF. Any claim to the contrary must use a site specifically designed to perform faster on Edge than on Chrome or FF.

    My strong recommendation for Microsoft: Just kill Edge. Simply acknowledge that Edge is just another miss like Internet Explorer. Just bundle links to Chrome and Firefox and make it easier for people to install those (even without having to use Edge first to download them).

  • @Manfred,
    You are mixing up 2 things, namely the bug described here and fixable by deselecting/turning off the “Show window contents while dragging” feature of the Visual Effects, as described above, and the (poor) quality of the Edge. The first one is related to poorly programmed GUI, and fixed by not using crappy GUI… partially.
    Microsoft has been forced into Edge by EU/US antimonopoly orders prohibiting them from pushing IE with Windows, because they abused their monopoly. Since many MS services are Web-based and they need a browser for them, so they came up with… Edge. It is still a piece of crap, but essential for them. In time and with complaints, like yours, they will fix it. Be patient or… else.
    Our priority here was to fix that stupid bug. Edge is especially bad when the computer is overtaxed, i.e. the RAM use reaches 90 %. Do try to add RAM. Do update other programs, esp. free ones. Decrease number of programs loaded automatically at the startup. Change your antivirus to Kaspersky, which taxes the least. Do avoid running with Edge other heavily taxing programs, like graphic ones, e.g. GIMP. Do check RAM use in the Task Mgr and replace big RAM users with better or simpler programs, e.g. paint.net instead of GIMP. Etc, etc.

    To make your laptop working faster, do go to Task Mgr > Process tab. Click on Memory tab to sort from bigger to smaller. If you see at the top a big memory user apps, which you do not use, go to Settings > Privacy > Background Apps and do turn them off there, e.g. Microsoft Photos, when you use a better app, e.g. paint.net.
