Then please see if the scenario in which this happens causes the
expose events to be delivered to Emacs by X.  If they are, the
function expose_frame should be called, and it should perform the
necessary redisplay.  If these events are not reported, Emacs has no
way of knowing that its frame(s) need to be redrawn.
