After latest updates the Wayland is using llvmpipe as renderer instead of the nvidia one. Seems the X11 are somehow working properly again and using expected renderer so switching back to X11 from Wayland. I was using Wayland because of the screen region issue topic here.
I did try to add nvidia-drm.modeset=1 to grub but no effect. Nvidia is selected via prime-select.
Additionally I was observing quite strange behavior using Wayland it looks like the whole session was randomly restarting during the usage and was asking for a password to open kdewallet right after the session restart ?!
