Hi Adrian Well... wayland works for me, and does a better job on scaling programs on a high density screen. So I keep it. The other effect I observed is that when screen was frozen in x11: I still could switch to a console (Alt-F1) and restart the whole X11 by killing the process "startplasma-x11". Of course, the session is gone then... I also tried to identify some root cause in the /var/log/messages or other places but was not successful. keeping old kernel versions: if you still have them on disk you can advise zypper not to purge it: add the kernel version explicitly tp the list in /etc/zypp/zypp.conf "multiversion.kernels = latest,latest-1,running" So if you happen to have an 5.8 kernel on an older btrfs-snapshot, you might want to roll back and ask zypper to keep the 5.8 kernel, then zypper dup again?

After switching to KDE-wayland the issue disappears, so it seems to be X11 related? Well, yes and no. You're right that the problem goes away switching to Wayland. However, downgrading the kernel to 5.8 helps as well - although don't know how to install older kernel versions in openSUSE since from the top of my head right now as the last reboot into kernel 5.9.x finally purged the last 5.8.x kernel image off my disk.
As for Wayland, it's still very rough for me. For example, moving an icon in the taskbar crashes Plasma completely, returning to the the display manager. So Wayland isn't an alternative either.
