Ive been following this bug for a while.
It seems to me that the bug does not occur while fullscreen video
playback, which includes fullscreen chrome youtube and netflix, as well
als fullscreen vlc playback. Can someone confirm? Hope this helps.
Is another bisect still needed? I might be able to do that.
