I've got two issues with freezes under zoom. Both started happening after I added a webcam to my system. Before I'd join the meeting with my iPad (for the camera) and my desktop (for screen sharing). Now with the web cam:
1. Randomly, my wireless mouse stops working. I need to unplug and plug in the receiver to get the mouse working again.
2. If I try to screen share, the zoom app freezes up and I need to force quit and rejoin the meeting.
I'm running Zoom client Version: 5.9.3 (1911) under Linux/debian.
