Steps to reproduce

  1. Go to
  2. Attempt to navigate through the UI
  3. For me, it is extremely unresponsive and slow. It takes nearly 10 seconds to BEGIN loading a page when navigated to.
  4. Hover effects on buttons do not show up because it is so slow.
  5. I am using a budget laptop from 2014 with a Celeron and 8gb RAM
  6. Using developer tools like Performance profiling are very slow
  7. Issue is only existent on
  8. This issue is also present on my other i5-6400, 8gb RAM, GTX 1050 machine
  9. The site uses nearly 50% of CPU and may spike up with no other tabs open.
  10. This problem is nonexistent on Google Chrome and Firefox Quantum

Bonus: Typing text is slow in YouTube as well. It takes 5 seconds after typing a string to begin displaying characters on the screen, which come up one-by-one 2 seconds apart for each. Sometimes the browser recovers the page when typing really fast.

  • I can confirm that performing a reset and/or repair on Microsoft Edge DOES NOT fix the issue. A temporary fix is to restore the legacy YouTube layout from the user menu.

  • Hello,

    Thank you for providing this information about the issue. We are unable to reproduce this problem in Edge. Since this is only happening on one site, let’s start by analyzing the site traffic. To do that, please perform a fiddler trace while repeating the repro steps, then attach the resulting SAZ file so we may investigate further.

    Please note that fiddler traces can share private information such as your login to YouTube and we recommend you prefix the name of your SAZ file with the word “private” and a hyphen (e.g. private-mytrace.saz) so that the file will not be viewable by the public. You may alternatively open a new private case and attach the file there instead, then report back with the new case number.

    Best Wishes,

  • Hello James,

    Many thanks for taking the initiative to help me resolve this issue. I have attached the Fiddler trace I recorded from YouTube. I can confirm that this issue is somewhat less noticeable on build 17604.1000 compared to the stable 16299 build. However, it remains present. Also, when upgrading my relatives’ mid-range computer to Windows 10 16299, this issue is very noticeable.

    I hope that this trace helps.

  • Hey James,

    I just wanted to check in on the status of this issue. Please let me know, as I will be more than happy to provide extra information.

  • Hello,

    The header response times and results from look fine, so next I am looking at the response times from other hosts which load with the site, such as ad services. I will let you know what I find.

  • Thanks for getting back to me.

    I’m no Microsoft Engineer, but I suspect that the problem is less of a response issue and more of an issue with the UI of YouTube using EdgeHTML. Again, it seems to be fine on Chrome and Firefox, but occurs only in Edge. (happens on work, other family members’ computers too) I’ll leave that up to your discretion ;)

  • Hello,

    Thank you for providing this information about the issue. Since it doesn’t happen to you in other browsers, I do not suspect network latency. Since it does not happen to us in our tests, I thought this might give us some clues to what you are experiencing. Unfortunately, I did not find anything unusual in the fiddler trace. Can you please use the Feedback Hub to collect more information?

    1. Open the Feedback Hub app on your device 
    2. Click on the “Feedback” tab 
    3. Click on the " Add new feedback" button 
    4. Click "Problem", fill in the title/details and select “Microsoft Edge” as the category and the appropriate sub-category 
    5. Under "Recreate the problem", press “Start capture” 
    6. Once the capture has started, run through the steps required to reproduce your issue 
    7. Click “Stop capture” back in the Feedback Hub app 
    8. Attach a screenshot of the behavior (e.g. CPU spike)
    9. Press “Submit” 

    This will provide us with a trace we can use to debug the issue further. Once you’ve submitted this, please paste a link to the newly created Feedback Hub issue in this bug so that we can link the two together and continue to investigate.

  • Hello community,

    I have an important update on this issue. After downgrading to the latest 16299 build, I saw a noticeable performance improvement on YouTube compared to the latest “Skip Ahead” build. Some aspects of the problem I faced are still present, so I will provide an updated list of them all below:

    1. Loading uses 75-80% of CPU for just one tab, but then it will return back to the typical 2-5% after page is rendered fully. (Usually after about 30 seconds)

    2. Clicking a button/link will still slowly load pages

    3. All animations on the page seem to have a 2-3 second delay before they run.

    Thanks for your help so far.

  • Let me know if I should post an updated ticket with this new information.

  • I can now confirm that this bug affects the legacy YouTube layout in Internet Explorer. Issue is present, but less severe.
    (Issue report details have been updated to include this new info)

  • Hey, are there any updates on this issue?

  • Microsoft Edge Team

    Changed Assigned To to “Travis L.”

  • Anyone? Hello

  • Classic YouTube layout used to work fine on Edge
    New YouTube layout is super laggy and slow on Edge
    The “restore old YouTube layout” option is no longer here… ☹

  • Still waiting on an updated response from Microsoft on this.

  • YouTube is barely usable now on Microsoft Edge after they forced us to use their new UI. runs slower on Edge than any other browser.
    Hopefully Microsoft will fix these issues in Spring Creators Update. ☹

  • same here, its unusable.

  • Dropping Edge and IE as they are unusable for many sites. Switching to Chrome

  • Have been using edge for more than a year, but not its seems unusable. youtube is so laggy that I would prefer not watching videos.
    switching to opera for now. Hopefully Microsoft can figure out a way to provide quicker updates for edge by making it a separate UWP app. I’ll try it again once the next update is released.

  • Hey everyone, thank you all so much for
    the feedback. We’re aware of the issue and are working on it, however it is more complex than one single issue. We’ll update this
    thread when we have an insider’s build that incorporates the work that should
    alleviate the issues you all have denoted below in hopes to get feedback from you all on the improvements. Thank you.

  • Some issues also happens on Twitch, when the Chat will spam a ton of emotes, Edge will have trouble displaying them, showing only gray blocks instead of the emotes and eventually hang. Typing is also slow sometimes, exactly as described on the original post.

    This issue doesn’t seem to be only on YouTube but everywhere, on heavy websites.

  • Hello, a lot of this may have to do with both IE and Edge not supporting the webcomponents specs. Namely the custom elements specification which has shipped in almost every major browser (with Firefox coming up on it too in the next few versions).

  • I can confirm this issue on my hardware.
    Its definitely edge,
    its not the network connection,
    It appeared with the last redesign of YouTube,
    All my systems are clean installed 1709!

    There must be some elements on YouTube, edge can’t handle properly.

    On my weak tablet I have to wait for half a minute, sometimes.
    Same there, a year ago everything worked flawless.
    And now, all websites are perfectly usable, but not YouTube.

  •  For those of you that missed my earlier comment,
    we are aware of this issue and it is due to many different issues. To the
    commenter above, they are partially correct in that YouTube is utilizing web
    components (specifically Custom Elements) and for browsers that don’t support
    it they are serving a polyfill (and thus the performance hit seen). The wrinkle
    here however, is that YouTube is using [1] [

    Custom Elements
    version of 0

    ]( which was not standardized by the W3C, [2] [

    HTML Imports

    ]( instead of the [

    newer ES6 Modules

    ]( which [

    Google should be using

     So even when we complete our implementation of web components we will
    still be served the polyfill as we will be supporting the standardized version,
    not Chrome’s proprietary implementation of it. This can be seen by other browsers
    that do support the necessary web component features are still served the
    polyfill. I hope this provides some clarity of the matter and we are looking at
    all of the various issues causing the perceived performance issues due to
    YouTube shipping their new architecture in the past year. Thank you.

  • Hey Greg,

    Thanks for taking the time to respond to the community on this issue.

    Since Google Chrome is utilizing a proprietary version of the web components specification, and YouTube is always serving Edge users a polyfill, is it possible that Microsoft will reach out to Google about considering the standardized components? And is there anything I can do as a user to help expedite this process?

  • You can upvote, or comment, to let YouTube quantify the impact of this on users here:!topic/youtube/JUlvC1MmLhs 

  • Updated to 1803 and the problem still exists. YouTube is so slow and laggy on Microsoft Edge.

  • Changed Status

  • YouTube is very usable on Firefox. I am reopening this issue as Microsoft needs to continue work on supporting the web components / optimizing for the polyfill. Details also updated to reflect the existence of this problem on Edge 17.17134.

  • It looks like YouTube relies on Polymer 1 which uses webcomponents v0. I’d assume that they’ll eventually upgrade to Polymer 2 or 3 which uses webcomponents v1. It might help if not now then in the future to support webcomponents v1

  • I agree. This issue should not be closed. If other browsers can solve this issue other than Chrome, Edge should be able to as well. If Microsoft is unwilling to ensure that the second most visited website on the internet does not work correctly on their browser, then they are telling me not to use it, which is a shame. If you need to use a proprietary Chromium component, then that’s what it takes.

  • same here painfully slow since xmas
    do an update works fine for a few hours and then its back to square 1

  • disabling adobe flash player seems to fix the issue

  • Hi, this problem isn’t new, or even “old” now. It’s happening since forever! Edge never worked correctly with YouTube. In the latest Windows 10 builds, it’s completely unusable. Using Chrome instead. I would prefer Edge because the low power consumption/better battery life and smooth scrolling, but as is, is a no go.


  • Hello guys! First, I’d like to say that I’m from Brazil, sorry about my bad English. Here, we’ve faced the same problem. It extends for all the google sevices, such as Google Drive, YouTube, etc. I was using Chrome since forever, but a few days ago I tried Edge. It seemed to be really good loading most of the sites I tested, but google services, oh God. I really wanna use it as my first option browser, but right now it seems impossible. Please Edge team, try to fix it asap, you will bring lots ppl to Edge fixing this issue.
    Thanks for all the work.

  • It is very unfortunate how Microsoft does not properly prioritize the quality of their products. Microsoft Windows 10 has always been very messy, and the same can be said about their flagship browser, Microsoft Edge. Although it has improved drastically since Windows version 1507, there is still very much to complain about. As of today, this browser is nothing but a disappointment. From the occasional hung pages, to the absolute incompatibility with YouTube’s components, I find it shocking that Microsoft is not investing more resources into the development of its flagship program, the internet browser. We are rapidly transitioning into a web-first world, and because of the problems above, future generations are being conditioned to click on the colorful Chrome icon over the first-party browser. This thought has made me, as a loyal Microsoft fan, feel deep sorrow about the future of this platform.

  • I agree with Luke.
    We’re building web applications on top of Microsoft stack, and like many other modern web applications we’re using web components. Microsoft’s done such a good job on modernising it’s backend web stack with Asp.Net Core but it’s embarrassing to tell clients they can’t use Edge because the browser is not yet ready to run modern applications. Not even using polyfills. Some clients aren’t in a position to choose another web browser than Edge (due to some company policy). So please, prioritise this issue. There will be more and more websites that are built on custom elements/web components.


  • I managed to reduce the effect by changing my ad blocking extension. I was using Adguard and changed to uBlock Origin. YouTube is now a little smoother, but still not as smooth as using Chrome or Firefox.

  • Hello,

    Thank you for providing information about the issue. We have confirmed the problem, and are working on a solution for Edge. We are resolving this issue as a duplicate of an existing case (# 13619513)
    . That case contains information for an approved feature design, rather than being an open bug report, so it is not publicly visible. We appreciate all the feedback, and look forward to delivering a better experience in an upcoming build of Edge.

  • Hello everyone! I have the same problem as you until i found on other website a fix that works well for me on Windows 10 (update 1803). Open run, press windows button +r and now type, or copy/paste this: inetcpl.cpl.
    You will get "Internet properties". Now select tab: "Advanced options". Find “Use Software rendering instead GPU rendering” option, (this should be on the top) check that box, apply and save. Restart Edge and that’s all. At least Youtube it works well.

  • Thanks for the tip Florea C.
    That worked for me as well and the experience is much smoother.
    The only downside, in my case, was that instead of using around 10% CPU for playing a video, it used about 60%

    Applying this solution made me really dream of having Edge opening YouTube smoothly like that with low CPU consumption :)

    Hopefully, soon.

  • I have the same issue, leaving this comment as a follow up.

  • I have the same issue, but I tried the fix with the software rendering: it didnt fix it, it was in fact slower than normal.
    Ive found out that the issues go away when I newly sign in to my YouTube account. If i leave it signed then it becomes slow again. So I think this has to do with cookies and caches and stuff, but dont quote me on that I’ve no idea how YouTubes netcode works :)

  • Also having this issue again, it’s annoying, have had this bug before but was gone for quite a while on recent versions. Changing to software rendering did not fix it for me.

  • Hello. Just dropped in while searching for a solution to this problem.

    I have the same issue but with an additional symptom. Whatever is causing YouTube to suddenly choke and put huge delays on typing, is also sending a lot of TDR errors to Windows. This occasionally forces the Nvidia drivers to reboot. I originally thought this was a hardware problem and replaced my MB, Ram, CPU, video card and power supply. All wasn’t for nothing though because my VR performance has been enhanced significantly, but I am much more confident assuming that the remaining TDR issue is being caused by playing YouTube through Edge.

  • "Display driver stopped responding and has successfully recovered".

    I’m also having the same problem with the display driver and the laggy YouTube performance on Edge. I wasn’t getting this error in the old YouTube UI.

  • Hello,

    So, as everybody here, I’m here to report that this ridiculous issue is still present. I really don’t understand how different things get broken and then not repaired with Windows10 updates…
    I used to use Edge as default browser, so links open in it instead of Chrome with xx tabs, but now it’s no faster to load a single Youtube link than those tens of Chrome tabs…


  • Changed Status

  • Reopening this issue, as we have not seen ANY Insider Builds that explicitly list this bug as resolved. This ticket was opened nearly 6 months ago, and this bug has been present in Microsoft Edge for even longer. I think some transparency is needed regarding the status of the duplicate that they are actively tracking. A developer on the Microsoft Edge team needs to give us a status update at the very minimum.

  • Windows 10 Pro 1803
    Microsoft Edge 42.17134.1.0
    Microsoft EdgeHTML 17.17134

    YouTube works much slower in Edge than in Chrome.

  • windows 10 pro 1803 with edge. would like to use edge as my default browser, but the laggyness in youtube is a no-go. please fix the problem!

  • I have this issue too, and have had it in my laptops entire lifetime. i7 7700HQ, 16gb, GTX1050

    This should NOT be an issue. For the first time I actually enjoyed using the new edge browser, but then this is my experience.

    Even though I really wanted to make the switch to edge, this problem is a deal breaker for me.

  • And I was all excited here, looking forward for my i7 8700K to arrive so I could use MS Edge. It seems that’s not going to happen, unfortunately :(
    Perhaps with the Intel core-X 10 cores / 20 threads then. Who knows :D
    Using web browsers nowadays is not cheap, I’m afraid

  • This solution with the tampermonkey script fixed the lagginess for me.

  • Thanks, Mario! The user script to disable Polymer really works.

  • Hello, everyone.

    Windows Central just did a very great article detailing the cause of the slowness. Yes, Microsoft is apparently not at fault. Some transparency from the Edge Team would have been nice, but hey that means this issue is no longer their problem, so I don’t blame them. Edge is actually a very nice browser. I force my family to use it ;)

  • Issue is still here. And twitch has problems too. But I saw that Microsoft is working on a Chromium based browser so hopefully that will fix this stuff.

  • Using edge with the latest updates and youtube is still super lagy. Its not hardware since im running a 1600X at 3.8ghz and a rx 580 8gb with 16gb 3200mhz ddr4 ram. Pleasae fix this its super annoying.

  • This won’t get fixed. They are going to thrash EdgeHTML and switch to Chromium. In my opinion bad decision.

    I’m using workaround - install Tampermonkey extension and put there script for disabling polymer:

    // ==UserScript==
    // @name         youtube_disable_polymer
    // @namespace    local
    // @version      0.1
    // @match        http*://**
    // @grant        none
    // @run-at       document-start
    // ==/UserScript==
    (function() {
        'use strict';
        var href = document.location.href;
        if (href.indexOf("/embed/") == -1) {
            if (href.indexOf("disable_polymer") == -1) {
                document.location += (href.indexOf("?") == -1 ? "?":"&") + "disable_polymer=1";

    IMO with this it looks much better and it loads basically instantly. I’m using this script also on Opera and Vivaldi.
