1598 is closed as fixed, and I have no idea how missing minimize/maximize
buttons are related to owned windows, and why you think that it's somehow
related to the visibility of an owner.

What you need to be fixed is making a zero sized window with WS_VISIBLE
style set mapped, but X11/WMs doesn't handle that gracefully.
