video showing visual bugs in Plasma when software rendering is active

SUMMARY
Setting Plasma Rendering Backend to "Software" causes many issues, including a reproducible crash in kwin_wayland as well as visual bugs in various applications.

STEPS TO REPRODUCE
kwin_wayland crash:
1. In the 'Plasma Renderer' settings application/dialog, set "Rendering Backend" to "Software"
2. Grab any window and drag it to the top of the screen to maximize it

More details here: https://discussion.fedoraproject.org/t/fixed-updating-kinoite-broke-things-not-even-a-rollback-fixes-it/123578

OBSERVED RESULT
kwin_wayland crashes / visual glitches occur (see attached video)

EXPECTED RESULT
window is maximized without crashing + visual glitches don't happen
