As far as i can tell, the flicker has been around since 1.1.5 at least. I have
no idea to whether it is a new old bug or a regression. This flicker bug does
affect quite some games on Mac OS X as far as I know.

DirectDrawRenderer=opengl
The flicker (& most of the time, supposedly also some random garbage from the
video memory) will always be present when the game runs under fullscreen mode.
NO flickering problem when the game runs in emulated virtual desktop mode.

Mac OS X 10.7.2 (64 bit)
