SUMMARY
Kwin's output is stuttery despite mangohud reporting a flat frametime graph.
It's genuinely awful.
STEPS TO REPRODUCE

2. Launch any game, and don't use any vsync, or freesync.

Awful frame time delivery
EXPECTED RESULT
Consistent frame times regardless of really any compositor, or no compositor.
