GPU resource starvation
Affected version
mutter 40, 41
Xorg, Wayland
Arch Linux
nvidia 495.29.05
Bug summary
Shell becomes unresponsive when GPU is under heavy load.
Steps to reproduce
- Visit https://testdrive-archive.azurewebsites.net/graphics/webglstresstest/
- Run test which will simulate a heavy load.
What happened
Shell becomes unresponsive for several seconds. On Xorg, the mouse cursor still works, but the shell and applications are frozen. On Wayland, everything, including the cursor is frozen. This only appears to affect graphics, since sound from background videos continue playing.
What did you expect to happen
Shell to remain responsive.
