Only on Plasma Xorg session not on Wayland nor on Gnome Xorg or wayland. Error on crash: Gdk-CRITICAL **: 10:51:45.466: gdk_surface_get_display: assertion 'GDK_IS_SURFACE (surface)' failed
I am not sure about 'Product' and 'Component' also I am sorry for the title. I just build gtk4 from git source and It is broken only on Plasma Xorg session.
About 'acting weird' it looks like mouse sometimes clicks somewhere else than cursor is pointing (or is not clicking at all) also gtk4-demo window cannot be moved without pressing 'Alt'
Does it work in a GNOME X11 session?
(In reply to Christoph Feck from comment #3) > Does it work in a GNOME X11 session? Yes, everything works.
Please report crashes in Gtk to Gtk developers.
(In reply to Martin Flöser from comment #5) > Please report crashes in Gtk to Gtk developers. I will, because the problem ocurs only on Plasma I assumed that it's Plasma's fault but I will take your advice.
