I can't determine exactly the angles this occurs but it does seem consistently the same angles on maps.
This is on Ubuntu Linux. I'm not sure what graphics card I have but expect it's the standard for this Dell Inspiron 530 = Nvidia GeForce 8300GS. No other problems, so expect it's a game bug.

Incidentally, the playdemo to record video, seems to only look to ~/.nexuiz/data rather than ~/.nexuiz/data/demos.
