Thanks. The vertical sync setting didn't change anything. I can still hear the
sound playing in the background, but I don't see anything rendered on screen. I
also checked the configuration file for the game, and I didn't find any
settings for the depth buffer or vsync. So I guess it could be possible that
the 16-bit depth buffer is breaking it? Any way to force a 24-bit instead, like
X11 does?
