SO, I've recently installed ubuntu on my laptop, installed the gfx drivers, and quake3.
Installed icculus quake3 etc.

Now, I get the following issue with both ioq3 and q31.32b:

The screen has black flashes, like extreme black tearing.

I have it at any resolution, and I've tried different gfx(r_) settings but that didnt do any good.

The problem also remains with r_swapinterval and r_fullscreen 0.

Halp?:D
