We can't reproduce this here, but you could try to add: QGL::setPreferredPaintEngine(QPaintEngine::OpenGL); before calling the QApplication constructor and see if that helps. If it helps, it means there's a problem with the new GL 2 paint engine on your system. If you give us the details of the graphics card and GL driver you're using, it might help us reproduce and fix it.
