The OpenGL surface stacking issues sound familiar, this is also hard/impossible to get right using Cocoa on Mac. One possible solution I've been considering is client side compositing: Create one OpenGL surface for each top-level QWindow, then render child QWindow raster content into a texture and OpenGL content into a FBO. Granted this moves you even further away from native x11 painting, but do you think it could be a feasible solution on the hardware you are working with?
