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.
It felt great to watch Gnome stumble after all the shit-talking, some schadenfreude was in order. I didn't care much for Windows 8; Vista was a the bigger mess of a release.
Plasma criticism was pointed and deliberate and grownup. Windows 8, less so.
The problem was that it was a bunch of people who had no good ideas and no insight trying to come up with new paradigms for interaction, and they were all bad. What the Linuxen desktops were doing was even worse than Win8, and the ones on that journey were all determined for some reason to deprecate the old WinXP clone UIs at the same time. Gnome really moved into a position of harassing and mocking its old users (basically regulation redhat behavior.)
