For some of our meetings we have been seeing reports from users that when they share their screens, the viewers can only see a black screen with a green outline rather than a view of the presenter’s screen. We saw this in meetings on the 24th and 25th specifically though we are continuing to hear of users encountering a black screen when presenting.
It seems to impact Chrome 80 on Windows Enterprise (though this could just be because most of our traffic comes from Chrome on Windows). The computers in question have integrated graphics and do not have nVidia. We have been in meetings where we could see the error but have been unable to reproduce the error in a reliable way. We have not seen any errors in the console. It does not seem to be caused by VPN since we have seen the issue on machines that are not using a VPN.
Has anyone seen this kind of issue before? Are there any areas we should start to look at to try to troubleshoot & diagnose the problem? Are there any common issues that could cause this type of behavior (apart from the graphics card that seems to be the problem)?
We are using the web sdk version 1.7.2
