            Bug ID: 770024
           Summary: Wayland: subsurface popovers cause warnings
    Classification: Platform
           Product: gtk+
           Version: unspecified
                OS: Linux
            Status: NEW

     GNOME version: ---

Best example is the volume button in the upper left of page2 of the
widget-factory.

In mutter, the popover shows up fine but clicking on one of the +/- buttons
causes the GtkApplicationWindow to be drawn without a current allocation and
the GtkScale doesn't properly update (unless one hovers the scale which causes
a queue_allocate iirc).

In weston, this is much more obvious since the entire window looks unfocused
after clicking one of the +/- buttons.

There are 2 if-statements in gtkwindow.c that cause the popover to be a
subsurface on waylsand, commenting both of them fixes these issues.
