log from opening the task switcher on an arch derived distro

SUMMARY
Issue with more evidence here: https://invent.kde.org/teams/plasma-mobile/issues/-/issues/282

Opening a KWin effect seems to show up black, with opengl errors in KWin (see attached)

This seems to occur on distros that don't compile Qt with the QT_FEATURE_opengles2=ON flag (ex. Arch). pmOS is fine, potentially because they do compile Qt with that flag.

STEPS TO REPRODUCE
1. Open a KWin effect (ex. task switcher on Plasma Mobile)

OBSERVED RESULT
It shows up black, but is interactable

EXPECTED RESULT
It displays the KWin effect

The log basically loops:
