Major graphical error on startup

[jim_the_coder]

Using the default preferences.txt (1024x768 not windowed), when I run the game I get a huge blur of colour which is what normally happens when I try to run something in a resolution/refresh rate my monitor can't support. Strangely, my monitor is capable of 1024x768 at up to 75Hz, so I'm not sure why this is happening. If I lower the res in the preferences file to 800x600 or just put 1024x768 into windowed mode, the problem goes away. I haven't noticed a refresh rate setting in preferences.txt...I'm guessing it's hardcoded into the game? My default desktop refresh rate is 75Hz, I've lowered it right back to 60Hz but I still get this problem.

I'm not sure what I need to submit here cos it's not technically crashing but it is making the game unplayable by default. If you need my system specs (you've already got them, right?) just say
