Maybe some of you have seen this problem before and can help me out.
I just did a fresh install of Fedora Core 2 Test 3 on my IBM Thinkpad T20. Now, whenever I move the mouse or a window around the screen, horizontal and vertical garbage lines show up and flicker for a moment. When I stop moving, they go away.
If there is something I can add to this post to help diagnose the problem, let me know.
