Gtk4-demo crashes a lot and is broken under KDE Plasma
- Start gtk4-demo built from git on KDE Plasma Xorg session
- Play with it for a while
- You notice that mouse clicks aren't going where mouse cursor is and gtk4-demo app crashes a lot with this error:
Gdk-CRITICAL **: 10:51:45.466: gdk_surface_get_display: assertion 'GDK_IS_SURFACE (surface)' failed
This only happens under Plasma Xorg Session. In every other session gtk4-demo works correctly. (Tested with Gnome Xorg and Wayland, Plasma Wayland(!) and Xfce4)
