Networked 'nedit' sessions display textual artifacts when "scrolling up". The best way I can describe the artifacts is that groups of text lines are repeated throughout the window.
Steps to reproduce:
ssh -Y somecomputer
nedit somefile.txt <--- do this on the remote computer
When nedit opens, scroll down to the middle of some text, then scroll up with either the mouse scroll wheel or using the keyboard up arrow to see the visual artifacts.
I have tried this with several remote computers all with different operating systems and different versions of nedit.
If I run nedit locally on my machine, these artifacts do not occur.
Also, I never had this problem before updating my computer from Feisty to Gutsy last week. I also tried using a different text editor remotely (xemacs), but this did not suffer the same problems.
My computer is running Kubuntu (Gutsy), with two monitors and an NVIDIA video card.

I also forgot to mention, the artifacts go away when you "scroll down". They scroll off the top of the screen like normal text and good text comes in from the bottom. As soon as you scroll up again, however, the entire screen is filled with repeated text once again.
