Sound/Graphics issues in cistern

[Havner]

The cistern level (not cistern entrance):

1. Sound, some loud statics, like one of the ambient sound files was broken. Hearable every few seconds.

2. Graphics, the light water reflections (torch light for example) sometimes does not look correctly, like the shader went nuts. Reflection becomes almost solid white/grey elipse with red/green colors on the borders.

None of these issues happens on windows installation on the same machine using the same save game.

Tried "reinstalling" the game, didn't help.

Computer is Early 2010 macbook pro 13" 2.4ghz, nvidia 320M. OS X 10.6.4 fully upgraded.

Game version 1.0.1.
