Summary: Depending on whether the underlying platform supports offscreen surfaces, QOffscreenSurface may create an invisible QWindow. In our case that's the case, for each offscreen surface a native window is created. This may lead to some funky results related to window decorations, see bug 407612. There are several ways to implement offscreen surfaces - either use pbuffers or utilize a surfaceless context extension. For the sake of simplicity this change sticks with pbuffers, but it's a good idea to support both methods.
