Description kodatarule 2021-09-17 05:43:18 UTC

SUMMARY
Sometimes when you boot into wayland session using NVIDIA it will set refresh rate to 60hz despite in the settings section saying it's 144hz, you can even check in ~/.local/share/kscreen that it actually reverted to 60hz and this happens 95% of the time on 5.22.90 which is a real shame as it finally resolved most of the wayland issues on NVIDIA.

STEPS TO REPRODUCE
1. Log into wayland session witness correct 144hz then reboot directly logging into wayland session(if you log into X11 and then back into wayland it'll resolve the issue)


OBSERVED RESULT
Logging into wayland session reverts from 144hz or anything higher than 60hz back to 60hz

EXPECTED RESULT
Refresh rate to stay at 144hz(or any other that the user is using)

For me, Wayland sessions reduced from 60 Hz (on Xorg) to 30 Hz maximum (available in settings) and logging into Xorg first then Wayland doesn't solve the issue.
