I'm almost certain that this is your problem.  You need to be doing these
commands in response to an Expose event (i.e. do an XtAddEventHandler to
your drawing area and put these commands into the event handler).
Otherwise, you're drawing into the window before it's shown up on the
screen.

You probably don't need the XFlush.
