High Rez Snapshot Artifacts

Has anyone gotten these annoying verticle black lines in high rez snapshots since the 1.7.4 - 1.8 upgrades? I know the issue is client side, and probably related to my hardware/driver configuration.

Rather than post a bunch of my system stats, I want to find out if anyone has had similar issues and what they did to fix them. I am currently narrowing down possibilities, and any input is greatly appreciated.

I figured it out. It was parent/child dual monitor display settings on my Nvidia 6800 Ultra vid card. I switched the diplay back to 1 of 2 instead of 2 of 2, and that did the trick
