Just reading content from web browser. Nothing more.

Some days ago I tried the plasma-wayland-integration. Didn't like it so I uninstalled it and went back to xorg. After that plasma likes to crash in various moments.

Please reproduce the issue with debugging symbols. Also, does it work again if you re-install said package?

I have installed those packages:
plasma-wayland-session
qt5-wayland
xorg-server-wayland

Now I'm using xorg and for 3 hours plasma's working fine without crash. Still testing.
If crash will happen I'll post logs with debugging symbols.

I couldn't get debugging symbols to work under Arch Linux so i tried to get those logs through 'gdb':
