When I try to run TrackMania in fullscreen, black bars (about 20-30px) appear at the top and bottom of the display, thus squishing the view a little bit. However, the mouse still functions as if the bars weren't there meaning that the accuracy of the mouse is a bit off. Not a very big issue because the buttons are quite big but still noticeable. This problem doesn't occur while in windowed mode. Running Crossover Mac 11.2.1 on OS X 10.8.2.
I can live with this problem, however I was wondering if there's anything I can do to fix this so I can add it as a hint.
For the rest the game runs great. I rate it as Silver.
