Problems with video playing on Mac

[ScoopArt]

First my specs:

OSX 10.6.8
Processor: 2Ghz Intel Core i7
Memory: 4GB 1333 MHz DDR3
Graphics: AMD Radeon 6490M / Intel HD Graphics 3000

As far as I know, all drivers are up to date.

Description of problem: There is a haze all over the video that changes colors constantly and flickers/flashes different colors. When I pick up the lantern, there is a sphere in the center of my vision (around the crosshair) where the image is more or less fine.

I have tried adjusting the video settings but nothing seems to correct the problem.
Attached is a screencap of the issue:

The sphere in the center looks normal, but everything around it is a color/light flickering/changing haze, The color changes as I change where I am looking.

Where should I go from here?

I still have not resolved this issue, the game remains more or less unplayable in it's current state. Has anyone else encountered this issue/found a solution?

The mac porter is looking into this, I sent him your details and I could also reproduce it on my Mac. So he knows about this and is working on it, I suspect it is not the easiest fix so it could take a while.
