-- Information about the crash:
SUMMARY
My Plasma has been crashing every time I wake up my dual DisplayPort monitors
on nVIDIA from sleep for the past few releases.
I suspect it started happening when I upgraded to Qt v5.15.3 a few months ago
and continues happening with Qt v5.15.4.
Blowing away ~/.config and creating new profile did not fix it.
STEPS TO REPRODUCE
1. Login to X11 session using dual monitors connected to nVIDIA video card via
DisplayPort cables.
2. Leave it idle until monitors go to sleep (desktop should be configured not
to go to sleep).
3. Wake monitors up and get back into the session (with or withour screen lock,
it doesn't matter).
OBSERVED RESULT
Plasma crashes every time, with taskbar, desktop icons and wallpapers all gone.
EXPECTED RESULT
No crash.
SOFTWARE/OS VERSIONS
X.org Version: 21.1.3
nVIDIA Drivers Version: 515.48.07
The crash can be reproduced every time.
