We have to be careful not to conflate multiple issues here. There are at
least two issues:
Video playback hangs the GPU. Most likely a Mesa issue.
Xorg cannot be restarted after that (you reported this upstream at
https://bugs.freedesktop.org/show_bug.cgi?id=99138), presumably a radeon
kernel driver issue.
