Chromium and Firefox freeze on edge if you play videos on external program (mpv)
I've been discussing this with @jeanlf at #11223 (comment 115270) but opening a new issue seemed best. The issue is not confirmed yet so it's useful if somebody could try to reproduce. It happens on latest edge and needs 1) a browser (firefox or chromium) and 2) mpv media player (s standalone program that plays videos).
Open browser -> Open video with mpv -> Close mpv -> Try using browser
Browser will be unusable and glitchy with constants freezes. Even restarting it won't help. The only solution is to restart Xorg.
Notice browser and mpv are completely different standalone programs and even after closing mpv the problem remains.
What I can't get over my head is that closing mpv and chromium doesn't fix the issue. You really have to restart Xorg. That's spooky.
