Very slow 3D performance after a while

NVIDIA Open GPU Kernel Modules Version

555.58

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.

Operating System and Version

Describe the bug

After a while of running any 3D app, performance starts to be very slow.

To Reproduce

After first boot, just play some demanding game. After about 10 minutes it suddenly starts going slow, as seen in this screencast.

On future reboots it seems harder to reproduce, so maybe a heating management issue.

Restarting nvidia-persistenced solves it immediately (systemctl restart nvidia-persistenced.service).

Restarting plasma-kwin_x11, or login out, doesn't.

Start by reviewing the linked nvidia-bug-report.log.gz and reproducing the slowdown with a demanding 3D game on the stated Arch Linux and Linux Zen setup. Compare behavior before and after restarting nvidia-persistenced.service, and use the screencast and reproduction details to investigate the performance change. Done means the reported slowdown is explained and addressed or the issue is narrowed with supporting evidence.
