Using Myth 1.7.2 on Mac OS X 10.6.8, ocasionally when I quit, the screen stays on what it was focusing on.
Sometimes it stays black, but I'm still able to use the finder to shut down/restart, but I can't see myself doing it.
One time, I lost a game, and quickly quit. Until I shut down, I could see nothing but a screen of myrkridia in muirthemne.
Annoying Bug
Re: Annoying Bug
Sounds like a graphics / OS bug. You should report it to Apple via:
