One more possibly relevant data point. Once the screen saver has
activated for mythwelcome (leaving the screen black), if I then launch
mythfrontend and then exit it, the main menu for mythfrontend remains
on the screen. The menu is not active, the screen is just not
repainted by mythwelcome. So essentially, once the screensaver
activates, the application will no longer paint the screen until it's
restarted.
