In that vein, another data point that may or may not be related. Using
the QT painter on mythwelcome, when I dismiss the screen saver by
pressing a button on the remote (usually a directional arrow key),
sometimes the screen flashes but the screen saver image stays up.
mythwelcome then responds to the SELECT to launch mythfrontend and
when I exit, mythwelcome is repainted.
