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.

Thanks.
