--- Comment #1 from Matt Fagnani <matt.fagn...@bell.net> ---
I reproduced this problem four times. I started as I described. When I clicked
on the Konsole icon in the task manager and Konsole disappeared and the
wallpaper was shown, kwin_wayland crashed sometimes with the kind of trace I
reported. Clicking on the Konsole icon about 12 times was the most it took for
the crash to happen. The following is the trace from coredumpctl gdb with
debuginfo packages installed manually.
Core was generated by `/usr/bin/kwin_wayland --wayland-fd 7 --socket wayland-0
--xwayland-fd 8 --xwayl'.
Program terminated with signal SIGSEGV, Segmentation fault.

There might be a race condition. The texture image in the trace might be the
wallpaper as the crash seemed to happen when clicking on the Konsole icon when
Konsole was shown so that it disappeared and the wallpaper was shown, but not
vice versa.
