Odd startup error

[Jehuty]

I get a bizzare graphical (or at least I assume to be graphical) error when I startup the game. The camera moves erratically around the screen without moving the mouse or the keys. Changing the resolution and whether or not the game opens in a window has no effect and as it's not a crash no error report is generated. The problem also appears to affect the sound, the funky plopping noise happens three times when the game starts as apposed to the once when played on my PC. I'm not too sure what else to include, if you need any more information I'll dig it out.
