While working with students I usually share my screen to display websites and sometimes videos. My Dell XPS 9350 (i7 6500U, HD 520 graphics) running Win 10 was capable of pushing the video or sharing static pages from my screen without a hitch. However, I've recently switched to LM 20.3 and unfortunately I cannot for the life of me share my screen in any meaningful way with people on my calls. If I share video, participants see a video with missed frames. Scrolling while sharing a website looks like screen tearing.
On LM 20.3 I've tried screen sharing using Google Meet on Firefox, Vivaldi, and Chrome without success. I've tried screensharing using Zoom from the Software Manager also without success. I also tried screensharing using Skype from the Snap store and that failed miserably as well.
I noticed a few posts here and on the web about problems with Zoom and Intel chips, but I haven't been able to understand what the actual problem is or if there is a solution.
Perhaps someone might be kind of enough to take the time to offer some clarification.
