Black rectangles appear when sharing screen

[Tomoya1]

When I share a screen in a meeting, other participants see black rectangles hiding the part of the shared screen, which is the video and toolbar in my vision.

I already tested many solutions by changing many settings (e.g., capture with window filtering, optimize to video sharing) to solve this issue, but it did not work for me. 

I would appreciate it if you showed me how to solve this issue.

Hello   @Tomoya1

I would visit the following articles/posts to see if the troubleshooting here assists:

• If you have a dual graphics machine—> select Integrated graphics, see this article https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0060527#collapsePC
• https://community.zoom.com/t5/Zoom-Meetings/Black-Box-while-screen-share/m-p/60077

Here are a few other points on this issue that I have seen recently that I would like to share:

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.

   1. https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html 

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.

 

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

 

1. 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.
2. If the above does not assist, you will need to create a case with Zoom Support as some cases need logs to be analyzed one by one. You can find out more on reaching support here: https://support.zoom.com/hc/en/contact?id=contact_us. 

Lastly, this screenshot should assist with some more detailed expected behaviors concerning this issue:

 

I hope this helps and please make sure to mark the solution as accepted if this information is what you needed.

Thank you,
