kwin_wayland crashes when trying to login into wayland session via SDDM. Output from journalctl --user -b: https://paste.sr.ht/blob/2eda1fc9ded14a3e17f39a2dd53d8da6e51bff0e

Seems like, I hit a bug fixed in 5.23.3, judging by this commit: https://invent.kde.org/plasma/kwin/-/commit/c4c03e2559f1ecf6f80ae965230bf0a19e17e210

It guards a function call of glDrawBuffer inside EglGbmBackend::makeContextCurrent, if the function is not available.
