[SOLVED] KDE/plasma: Strange behaviour since last update

Hej, just updated the system (last update 2 days ago), bunch of plasma and other display related stuff was on the list.
Since then any application - e.g. Konsole, Dolphin, firefox, sublime text - is not usable/not refreshing when the window is maximized.

Any ideas where to look?

Cross-checked with xfce4 - there everything works as expected.

xf86-video-intel? Try removing that, it's unmaintained and known for variety of issues here.

If this isn't it post your xorg.log and

sudo journalctl -b

during reproduction.  https://wiki.archlinux.org/title/Xorg#General https://wiki.archlinux.org/title/List_o … n_services

Thanks to V1del for pointing me to

sudo systemctl -b

.
While reproducing the issue I've seen a few lines of

Which led me after a short search to https://bugs.kde.org/show_bug.cgi?id=461029

Short check:

[marcus@lep50 ~]$ pacman -Qi kwin

So it's either roll back or wait for fix, because the report timestamp is after build timestamp.
