I found some info at https://developer.gnome.org/gdk2/2.24/ and
subpages. Don't know if it's relevant.
#define gdk_window_get_size gdk_drawable_get_size
From the description of gdk_drawable_get_size():
On the X11 platform, if drawable is a GdkWindow, the returned size
is the size reported in the most-recently-processed configure event,
rather than the current size on the X server.
From the description of gdk_window_get_geometry():
On the X11 platform, the geometry is obtained from the X server, so
reflects the latest position of window; this may be out-of-sync with
the position of window delivered in the most-recently-processed
GdkEventConfigure. gdk_window_get_position() in contrast gets the
position from the most recent configure event.
