KDE/Plasma crashes frequently. Other applications on the desktop are still usable. But switching apps using Alt-Tab creates funny patterns. And the taskbar has gone. KDE/Plasma has been unstable for a long time on my system. I guess since OpenSuSE Leap 42.1. I tried various plasma updates there. It kept unstable on OpenSuSE Leap 42.2. And got worse on OpenSuSE 42.3 Gnome had issues, too. Maybe I'll give it a try again.

Please attach the file '/sys/class/drm/card0/error' following the hang; it is vital for triaging.

From openSuSE Release-Notes: "On openSUSE Leap 42.3, the upgrade of the graphics stack up to 4.9.x kernel code is provided via the package drm-kmp-default instead of backporting tons of patches into the kernel itself. ... If you often face critical issues, like a hung GPU, try to uninstall the package once like below, reboot and retest." That's what I did now. If you need additional information about the bug, I'll be happy to reinstall drm-kmp-default and try to reproduce it.
