SUMMARY
After upgrading Plasma from 6.1.5 -> 6.2, it became unusable as kwin_wayland is
consuming all my CPU. I'm running a VM (under QEMU) with 4x CPUs allocated to
it and it was fine before the upgrade, now Wayland is unusable but X11 is fine.
STEPS TO REPRODUCE
1. Login to a Wayland session.
OBSERVED RESULT
See attachment but kwin_wayland is consuming all my CPU resources, yielding the
system nigh unusable.
EXPECTED RESULT
kwin_wayland would consume some small percentage of CPU.
