GTK4 windows appear "stuck" to top-left corner in Xorg sessions
GNOME 3.38.1 Xorg, Solus 4, GTK 4.0
One of the bugs with Gtk4 applications under Xorg is that they appear to be un-movable from the top-left corner (at least in Mutter), unless they are maximized and normalized again with keyboard shortcuts, or the window is put in background and back.
This seems to be only a regression of some latest (3.99.0+?) versions, since it worked normally last year.
