Hi, just an idea, but obviously somewhere deep inside Qt's bowels (rather, the painting system) there's knowledge of which window obscures which etc.
There isn't. Compositing window managers have been a reality on desktop machines since Mac OS X 10.2 (2002), maybe even before that.
The only really robust approach is asking the WM what are the visible windows and their stacking order. Keeping the order in Qt is also feasable, modulo of course bugs in the Qt / WM interaction...
