Re: 180.08 & red checkerboard
Hm, no compositing working, since it won't do with both the 8600 and the 6200 in the system. (no GL on the 6200 either, so glxgears only shows an image on the 8600 screens, but remains black on the 6200 screen)
What really strikes me is on what causes this pattern. The size of the squares is 16x16 pixels, but they aren't completely opaque, but slightly translucent, so I reckon it must be something from the driver.
