is a board where a number of people have posted with (apparently) the same problem.
I have horizontal gray lines that run across my screen. They correspond to dark parts of it.
e.g, a line of text on a white background will have a dark horizontal line the height of the text along the entire length of the screen.
Has anyone else run into this? More importantly, has anyone fixed this?
I'm running the latest X, GLX, and drivers on gentoo.
