[Wayland-bugs] [Bug 770024] Wayland: subsurface popovers cause warnings

[gtk+ (GNOME Bugzilla)]

--- Comment #3 from Timm Bäder <mail at baedert.org> ---
So it looks like I can effectively "solve" this by...

  1) commenting the loop at
https://git.gnome.org/browse/gtk+/tree/gtk/gtkwindow.c#n7400 . This will cause
the popovers to be realized at a later stage, namely in
_gtk_window_set_popover_position here:
https://git.gnome.org/browse/gtk+/tree/gtk/gtkwindow.c#n12283 .
  2) Stop the popover from listening to the "parent's" size-allocate by
commenting https://git.gnome.org/browse/gtk+/tree/gtk/gtkpopover.c#n2058 . The
call to gtk_popover_update_position here might later cause another
gtk_widget_queue_resize() through _gtk_window_set_popover_position during a
size-allocate though I'm not sure if that's the cause.


This is tested with the volumebutton popovers in the widget-factory. The
popovers will now popup in the upper left corner.
