This looks like the common problem one encounters when running X.  If one tries
to draw something after the window is created and mapped, it most likely will
get thrown away.  The correct thing to do is, after the mapwindow request, to
wait for the expose event from the server.  It is only after the initial expose
event that drawing can be done.  This probably explains why you are not seeing
the rectangle being drawn.  If you single-step it in the debugger, it will
probably work since the expose event will be sent before you perform the
drawing operation.
