SUMMARY
When moving the mouse, a single core is being fully utilized by kwin_wayland.
When using Plasma on X11 on the same machine, this does not happen.
STEPS TO REPRODUCE
1. log in with plasma wayland
2. run top
3. move mouse around constantly for more than a second
OBSERVED RESULT
A single core being fully utilized at 100% by kwin_wayland
EXPECTED RESULT
The mouse moving around shouldn't use that much CPU, as it doesn't on X11.
