Stack trace of crash
SUMMARY
This behavior only started with the nvidia 450.57 driver. Everytime I wake from
suspend, I get the message 'Desktop effects were restarted due to graphics
reset'. But then if I go to KDE Settings, the left panel are all black. If I
restart kwin_x11 by issuing kwin_x11 --replace, kwin_x11 crashes. I have
attached a coredump of the crash.
STEPS TO REPRODUCE
1. Put desktop to Sleep
2. Wake up
3. Restart kwin_x11 with kwin_x11 --replace
OBSERVED RESULT
Upon wakeup, I get the message 'Desktop effects were restarted due to graphics
reset.
kwin_x11 --replace produces a crash.
Note that this behavior only started with the nvidia-450.57 driver. I
downgraded previous driver to test and there are no problems.
EXPECTED RESULT
There shouldn't be any message 'Desktop effects were restarted due to graphics
reset'.
kwin_x11 --replace shouldn't crash
