Question

Shadow blocks on participants screens when sharing video

Hi, I am running a weekly series of sessions which involves screen sharing a video. The second session last night had issues where some participants had shadow blocks on their screens, and were also aware if my mouse pointer moved. This did not happen the first week. I tried ticking and unticking the Optimise for video check box which did not seem to help. Any ideas?

    Hi @psbw 

     

    Go into your local Zoom Settings > Share Screen > and un-check "Show my Zoom Windows to other participants".

     

     

    That should fix your problem.

      I also have this problem since the update to Zoom workplace. Anytime I share my screen my viewers see black boxes where the zoom menu toolbar is. And also - critical to the way I use Zoom as a teacher - if I have the gallery view popup on the screen that also shows up as a black box. So either my participants can't see what I am showing them, or I can't see my participants, neither one of which is acceptable.

       

      I have the latest update. I've turned off all hardware acceleration settings, ensured "video optimization" is not set, and made sure "show zoom window when sharing" is unchecked. I've been using Zoom in the exact same way since early in 2020 and never had this problem until now. Nothing I'm doing is different, so it's definitely something different on the Zoom end.

        Yes, precisely the same problem. I removed and reinstalled it many times to see if that fixes it but no luck. I cannot find the previous version to go back to.

        I have a web ticket open with Zoom support, and I'll point them at this thread so they can see that it's not just me.

          Hello there,

          I'm sorry for the inconvenience and late response.

          Kindly follow these troubleshooting steps:

          1. If your CPU is Intel Iris Xe Graphic, please update the driver to the latest version, Intel fixed a problem in 32.0.101.5972; this fix is for this CPU type only.

          2. If you don't check the setting Show my Zoom windows to other participants when I am screen sharing, but you check the optimize for video clip option when sharing, it is expected behavior that others will see the grey when Zoom windows are in the front.

             

             


             
             

          3. Go to Client Settings->Share Screen->Advanced and select Auto mode Screen capture mode and turn on hardware acceleration for Screen sharing

             

          4. Dual graphics machine—> select Integrated graphics, see this article

          5. If a remote desktop client joins the meeting and sharing screen, it is possible that others see the grey box due to the presenter’s virtual graphic.

          6. Other cases need logs to be analyzed one by one.

          Check settings to see if it is expected behavior; there is one case that is expected.

           
           

          Settings

           

          Option “Optimize for video sharing” when sharing checked

           

          Option “Optimize for video sharing” when sharing unchecked

           

          “Show my Zoom windows to other participants when I am screen sharing” in client settings checked

          No grey box should be seen

          No grey box should be seen

          “Show my Zoom windows to other participants when I am screen sharing” in client settings unchecked

          user will see a gray box, this is expected behavior, use the other setting combinations for workaround.

          No grey box should be seen



          Please let us know if this helped.

          This did finally work for me. Although this is not the "latest driver" so I hope they propagate the change to the most recent versions as well, so I don't keep having to downgrade.
