I can reproduce the hang in QQuickWindowPrivate::polishItems() by simply suspending to RAM and resuming my machine. Then some notification appears, but isn't drawn: just a rectangle with garbage contents, and plasma is hung. I attach to it via gdb, and repeatedly executing "fin" command finally shows that the hanging function is QQuickWindowPrivate::polishItems().
