When the issue occurs it will generally never go away until one of the things happen:
- restart x a couple of times(reboot, ctrl alt backspace)
- reseeding of video card, ram, second cpu. can stop this or lessen the issue.
- Swapping out a monitor. i.e. I swapped out my monitor today with a samsung syncmaster 2443 to the display port. The secondary(DVI -> DVI) monitor is a HP LP2464, which has the pink/green pixels is now completely gone.

No, we do not have any conclusive evidence to what actually causes it to happen. I speculate something in the monitor may not be communicating with the graphics card.

I mention earlier of some of the computers running a kvm with windows, when swapped back into windows both monitors display properly. Then in linux you see the graphics pink/green pixels.
