This appears to be the same as the Closed bug
https://bugzilla.opensuse.org/show_bug.cgi?id=905305
I don't believe it's restricted to KDE but it's a while since I've tried other
desktops.
Reproducible: Sometimes
Steps to Reproduce:
Dragging windows about or playing videos makes it more likely to happen.
Red Hat have released a possible fix for this problem, among others, in their
"Xorg server and driver bug fix and enhancement update"
https://rhn.redhat.com/errata/RHEA-2015-2198.html
In particular, Red Hat 1185807 - cannot show login page again of KVM guest
(spice+qxl) after log out from guest's desktop
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=1185807
and possibly:
Due to a memory leak in the QXL driver, an X.Org guest could terminate
unexpectedly. This update fixes the memory leak, and X.Org no longer crashes.
(BZ#1222038)
I am not authorized to access bug #1222038.
Would it be possible to port these fixes to openSUSE?
