: but whenever this window is overlaped by some other window it gets : repainted by that overlapping window colour.
That is proper behaviour. By setting a window property bit to NOBACKGROUND, the system won't automatically paint a background for it. However, when a window overlaps that window, of course it will be fully displayed on top of it. When that overlapping window is removed, the original window will be sent an EXPOSE event, without clearing the background. That window is fully responsible to paint its window contents.
