Not as long as we do pure X-calls on Gtk-widgets.  For this case, the widget thinks that nothing has been written to it (i.e. no Gtk+ methods have been called to do so), so the expose event does not need to redraw or clear anything.  But we have  written something, but with X calls, and the widget can't know this.
