Comment 0 for bug 1260827

When a window is open periodically horizontal corruption occurs on all the screens in this 3 monitor setup. I also see corruption more like a static in the shadow background on the game Kerbal Space Program.

The hardware config is three Samsung SynMaster XL2370 in a 5380 x 1080 configuration running off of first of the two XFX HD 5970 cards attached via two DVI ports and one display port using an active DVI to display port adapter.

See attached screencaptures for details.
