SUMMARY
Since upgrading my laptop to Plasma 6, the compositor performance in X11 has
become very choppy. I previously had smooth 60 fps for desktop effects, but now
I get around 32-35 fps when moving a window around and 45-50 fps when doing
nothing. Switching to Wayland, everything stays at a smooth 60 fps.
Here is a video comparing X11 vs. Wayland performance on my laptop:
