Bug 422904

SUMMARY
After I log in to a Plasma Wayland session on NVIDIA, _sometimes_ I'd get a dark screen, with only the mouse cursor being displayed. However, trying to double or right click does nothing, so I essentially end up with a broken Plasma session, with the only option being rebooting my computer. Unfortunately, though, I haven't found a consistent way to reproduce this yet.

Additionally, a bunch of KDE components seem to fail after ksplashqml crashes (though I'm not experienced enough on debugging to precisely confirm the crash order of these compoenents). coredumpctl shows me this:

In my next e-mails, I'll be attaching full gdb backtraces (with symbols) for all these processes, starting from the lowest pid.
