output from systemd-coredump for three crashes
SUMMARY
I run KDE on a laptop, which I periodically attach to a 4K monitor/keyboard
using a USB 3.0 hub.
If I use my laptop standalone, allow it to go into standby, then connect to the
monitor, when it wakes, kwin dumps core fairly frequently (I can't be sure that
it's every time, but certainly frequently enough that I now avoid the scenario
entirely if possible).
Under the following scenario:
* use laptop standalone
* allow laptop to go into standby
* connect laptop to hub
* wake up laptop
STEPS TO REPRODUCE
1. use laptop standalone
2. allow laptop to go into standby
3. connect laptop to hub
4. wake up laptop and enter credentials
OBSERVED RESULT
kwin_wayland dumps core and restarts, apps require restart
EXPECTED RESULT
kwin_wayland doesn't dump core
