Bad compilation options, and/or bad driver/firmware interactions.

I'm using it on CachyOS with on old intels(Kaby Lake Core i5-7500t/Core i7-7700t) with old intel integrated graphics(HD630), and it never did that. Since early Plasma6/late Plasma5 times. Cant recall exactly anymore, for about 2 years now. In fact, since Plasma6 it reminded me of the good old KDE3 days, again. Except for the memory usage maybe. OTOH the systems have much more memory since the times of KDE3, so shrug?

If everything else fails, there is still https://www.trinitydesktop.org btw.
