I encounter this problem from time to time:
When I turn on the screen share, show windows and switch between them, other conference participants at some point stop seeing my demonstration. This changes the connection status of my user to “lost”. After updating the web page of the conference, the problem goes away for a while.
I am using Jitsi Meet stack on Docker. The version of the images is stable-7001.
Maybe someone came across a similar behavior of screen sharing. In what direction to look for a problem?
