You mean you don't have any window manager at all ?

Try with this signal:
http://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget-map-event
your problem could be cause "configure-event" call it's handlers at
the last stage of emission:
"G_SIGNAL_RUN_LAST     Invoke the object method handler in the third
emission stage."

About this can't assure you anything but you should check cairo API
for a method like the one you want.
