Title:
Xorg 100% CPU and frozen desktop after closing chromium
Status in chromium-browser package in Ubuntu:
Confirmed
Bug description:
chromium 118.0.5966.0 2604 latest/edge
Whenever I use chromium in a video session (meet, youtube) that used
hardware acceleration, for a long time (like 20min or more), and then
close it, the whole desktop freezes, and the laptop fan turns on.
Logging in remotely I see that Xorg is at 100% CPU.
The rest of the system is operational, but nothing graphical is. Just
the mouse cursor moves around.
SOMETIMES, if I wait a few minutes, Xorg resumes behaving normally,
and I can use the desktop again, but most of the time I have to login
remotely and kill -9 xorg (plain kill won't do it).
With wayland, this does not happen. This could very well be an Xorg
bug, but filing here first for visibility.
