I am running Fedora 14 on a Dell Precision Work station.
When I scroll in in firefox, the windows gets messed up. Some lines are repeated and cover others up. It looks sort of like a visual stutter.
It seems to happen primarily when I scroll using the middle mouse button. It doesn't seem to happen in other applications such as Adove Reader.
Can anyone suggest what the problem might be?
Added later: I may have fixed it by changing my mouse settings. I slowed it down and increased sensitivity, both slightly I don't know which did it.
