Whenever I try to change the background colour from white to grey or black (or when the game does that by default, such as ninja mono mode), the screen goes completely blank, apart from the black bar on the bottom stating the name of the current song. The game seems to run normally, but I can't see anything. This only happens when Premium graphics settings are selected. When I downgrade settings to Enhanced, everything is back to normal. Resolution, fullscreen mode or antialiasing don't affect the issue.
I have a Radeon HD 3870 and the latest Catalyst drivers, version 8.4.
