Hello, This problem appears on a fresh Debian 6 install -- it is intermittent and the position of the white lines vary. I can not track the source of the problem and it seems to affect all fonts at some time or the other. This picture will explain it much better than words: http://www.flickr.com/photos/abhidg/5482331816/ An initial search did not get me any cases where people have experienced this problem. -- Abhishek Please CC any replies!
