urgent:sun graphics doing strange things

[MaxIP]

Hi
I was just browsing couple of directories when all of a sudden, lines of yellow'ness apperaed across the console.
I tried a different workspace.
Same problem.
Tried a different monitor and cable.
However when I use KDE as the desktop everything is fine.
Could this be an isolated CDE problem.
Has anyone else had this problem

thanks

I spoke to soon.
The problem also appears in KDE.
Whenever I am scrolling that section of the windows gets tinted yellow.

This has never happened before.
