  • Hi Shaaz,

    I was able to repro this even without using RDP, see the attached output file.  Have you run this locally?

    Also, have you tried this with any other languages besides C#?

    Appreciate the submission,


  • I did a little more research and testing on this and discovered that adding a Thread.Sleep() corrected the issue for me.  Can you try the same test and let me know?

                Screenshot getScreen = ((ITakesScreenshotdriver).GetScreenshot();
                getScreen.SaveAsFile(path, ScreenshotImageFormat.Png);

  • Hi Steven,
    When i run locally it is able to capture correct screenshot, but it always creates blank screen when run on a remote desktop and disconnected it. Tried with "Thred.sleep()" and still blank screens are getting on Remote desktop

  • Attached screenshots captured when Remote desktop connected and disconnected.

    At the moment i don’t have any setup to run on java or any other languages other than C#.

    Any fix for this would be a great help

  • Thank you for the update.  Using another language is not required, just curious, in case the issue is related to the language binding.  I am also testing with Java.

    I test locally first to make sure it isn’t a basic use case issue.  I will test using RDP.

  • Can you give me information on your power configuration for the remote system?  for example, is the system set to hybernate or sleep after so many minutes?

    You can use Windows Settings GUI to get this or using powershell.

    powercfg -Query

    There are also two reports that can be collected.


  • I could collect log using “powercfg -Query” and the same is attched for your reference.
    While trying other two reports i am getting error “This command requires administrator privileges and must be executed from an elevated command prompt.” though i have administrator privilage

  • This could be because of the default powershell folder is C:\Windows\system32.  Can you try running the command in your home or Documents directory?

    cd C:\Users<your_username>\Documents

    If that doesn’t work, check your ExecutionPolicy and set it temporarily to ByPass and run again.

    Get-ExecutionPolicy -List
    Set-ExecutionPolicy -ExecutionPolicy ByPass

  • Forgot to ask if you are using the default Windows RDP client?  Also, what is the version of Windows 10 on the remote test machine?  Is the remote machine a physical computer or a VM?

  • How is the remote machine connected to the network?  E.g. Ethernet or Wifi?

    The remote machine is on AC Power?

  • I am using default windows RDP client.
    Version 1703(OS Build 15063.608).
    Remote machine is a physical computer and is connected to network by Ethernet.

  • Steven, just curious to know, why only Edge webdriver has these much dependencies like power configurations and all. It is able to get screenshots in this case using Chrome, Firefox and IE web drivers :(

  • Well… because I didn’t think that through very well. :-/

    So great point.  I was trying to figure out why it is happening for you on an RDP session for a physical machine and not happening for an RDP session for a VM/Hyper-V session, i.e. that is how I have been testing.

    I need to reproduce this issue to get is worked on.  I will run on a physical machine using RDP.  Appreciate the help and gentle logic feedback.  :-)


  • Having the same issue with but with Internet Explorer.
    On Remote Desktop, the screenshots works fine with Chrome & Firefox, but provides Black screenshots with Internet Explorer.

  • Hi Gunjan,

    It’s bcoz once screen gets locked, Windows machine not allowed you to take screen shots on IE browser.
    You have to keep widows session active even after getting disconnected from RDP client.
    Please keep below commands in a batch file and run to disconnect from RDP client so your current session will unlocked.

    C:\Windows\System32\tscon.exe rdp-tcp#1 /dest:console
    timeout 10
    QRes.exe /x 1920 /y 1080

    NOTE: U can check this issue by connecting to your Windows machine through RDP client and execute then u’ll get actual screenshots. Again execute same script after disconnecting from RDP client, now u’ll get blank screen shots.
