The attempt: To run the game an any video sub-system installed on a computer in full screen mode. The problem: Graphical anomalies on the non-primary video card. Mainly the back-buffer seems to be "merged" with the primary surface. The solution: This is where you come in. I have no idea why this is happening or how to go about solving it. If you have had a similar problem and know a trick then sharing your knowledge would be appreciated =)
