I've searched the forum but I haven't been able to find anybody who has reported this.
When I run an opengl app (Extreme Tuxracer, Astromenace) then strange graphical glitches appear every now and again. They look like infinite perspective tunnels shooting out of vertexes.
I am aware that F12 used bleeding edge Intel drivers:
Is this a glitch in the new drivers?
Edit: Here's a screenshot. I made the screenshot in windowed mode. The gitches also appear in fullscreen mode.
Edit: And here are a couple of good ones from Astromenace.
