I tested multiple times this scenario: i test with multiple browsers and computers to simulate when my family will join. There are 4 concurrent users. Most of the thumbnails are 640x360 like configured, but some are at 180. When double clicking them it gets to the full screen. When I go back to tile view now the resolution becomes 640x360 for that one as well. So we have this workaround but I am wondering if i can do anything on the server side so that it can improve the quality automatically,
Are you using jitsi on meet.jit.si or you have your own installation?
My own, it’s happening also when I switched to a bigger machine, MBP, 8GB RAM, 8 physical threads.
Okay, others have reported this same finding. I haven’t come across a definitive fix in my reading, but you should check out this thread for some of the steps the OP took: Resolution Problem and CPU problem
