Skip QWSIF::WindowScreenChanged events if the screen is unchanged
WindowScreenChanged events might be reported repeatedly from the QPA backends
until the event has reached GuiApplicationPrivate::processWindowScreenChangedEvent()
which sets the screen. Ignore events in case the screen is already correct.
