-- Information about the crash:
- What I was doing when the application crashed:
After I login to the KDE wayland I see plasma crashes after I interact with panel.
For example after clicking on the tray expand button (triangle).
Also I see visual glitches after tray panel is vanished.

I have nvidia driver version 440.59 installed & egl-wayland-1.1.4.
