SUMMARY
When running a nested kwin_wayland compositor the nested compositor defaults to
running at 60hz. There is no option in kwin_wayland to override this default.
This is problematic as applications running inside of a nested flicker heavily
when the kwin_wayland window is on a higher refresh rate monitor. The issue
does not occur when the window is on a 60hz monitor nor does it happen when the
application inside of kwin_wayland is ran directly on the hosts wayland socket.
STEPS TO REPRODUCE
1. Start kwin_wayland
2. stats applications inside the kwin_wayland window
OBSERVED RESULT
kwin_wayland runs at 60hz confirmed by kscreen-doctor -o
EXPECTED RESULT
kwin_wayland should run at the refresh rate of the display
