bug#52705: 29.0.50; Flashing popups when x-gtk-use-system-tooltips is nil in pgtk

[martin rudalics]

>> (emacs:1348): Gdk-CRITICAL **: 09:25:18.556: 
gdk_window_create_similar_surface: assertion 'GDK_IS_WINDOW (window)' failed
>
> That points to the tooltip's window not being realized when
> `pgtk_begin_cr_clip' is called, which "can't happen".
>
> Can you run Emacs inside a debugger with the environment containing
> `G_DEBUG=fatal-criticals' and show a backtrace?
