Thanks, but that doesn't make much sense.  Updating a window's opaque
region by calling its `style_changed' function shouldn't interfere with
updating it or changing its size.

What happens if you comment out this part out?

      object_class = G_OBJECT_GET_CLASS (FRAME_GTK_OUTER_WIDGET (f));
      class = GTK_WIDGET_CLASS (object_class);

      if (class->style_updated)
        class->style_updated (FRAME_GTK_OUTER_WIDGET (f));

Thanks.
