screenshot from the intro sequence, notice the vertical lines

Hi there,

I've set the component to d3d because that's most likely the thing where the
problem originates problem. I'm not completly sure about it, so if someone can
identify a different component then please switch it.

The problems are visual errors in the old DirectX game AvP1 (the alien demo).

Both vertical lines of different color appear and flickering artifacts. See the
screenshots for a better explanation.

The problem does not only appear with AvP1 but also with the System Shock 2
demo, but there we have some more problems.

The demo is free to download from FilePlanet (you just need a (free) account).
I didn't try finding other mirrors.

I also want to point out that the number of lines on the screen seems to be
related to the overall brightness of the screen content. During the startup
sequence of the AvP1 demo a movie is played, producing a sort of lightning
effect which illuminates the screen and therefore increases brightness a lot.
During this lightning the number of lines explodes.

I'm still trying to capture this, but I'm having a hard time finding the right
moment to take a screenshot.

Tests were done on a i915 with:
mesa-7.0.3
xf86-video-intel-2.3.0
