Running Nvidia Wayland

You need a very up-to-date Qt. Make sure you have > Qt5.15.0 or 4bd13402f0293e85b8dfdf92254e250ac28094c7 cherry-picked.

Check our driver is running in modesettings mode

"cat /sys/module/nvidia_drm/parameters/modeset"

It should print "Y"

If not, modify your kernel command line and add the line nvidia-drm.modeset=1. Search for "kernel parameters" in your distribution https://wiki.archlinux.org/index.php/Kernel_parameters is a good starting point

You should set the environment variable "KWIN_DRM_USE_EGL_STREAMS=1"

The easiest place is to add a file /etc/profile.d/kwin.sh with the line export KWIN_DRM_USE_EGL_STREAMS=1

Verify this is working with the command line tool "env" after rebooting.
