Fullscreen broken in OS X 10.6.8 / Snow Leopard

[jens]

I tried 1.2.1 on 10.6.8, with radeon 4670 and it worked fine, my native is 1920x1080 however. Did you try running in 1680×1050 (the next 16:10 resolution from 1920x1200)? Any programs running on the computer that could possibly interfere? Perhaps some settings with the display/user interface (increased the font size or similar) that is not standard? Did you try to reboot the computer to make sure it was "fresh" before running the game?
