I know this is a really specific problem, but here goes.

Here's a example.

When using Photoshop CS6 x64 with the "Use Graphics Processor" is turned on, some photos (maybe 1 in 1000) will have black artifacts in it. If I open the photo in Picasa, GIMP or Paint, it doesn't have any artifacts. If I turn off "Use Graphics Processor" the issue goes away as well.

The cards are 2 x 7970 in crossfire.
 
5.- If you are using more than one video adapter, remove the additional cards.
Multiple video adapters can cause problems with GPU accelerated or enabled features in Photoshop. It's best to connect two (or more) monitors into one video adapter. If you have to use more than one video adapter, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop.
Note: Using two video adapters does not enhance Photoshop's performance.

Straigth from Adobe's mouth.

They use cuda in windows, opencl on apple for CS6, gotta wait for the next release for proper OpenCL support.

I don't use Photoshop, but if you install AMD's OpenCL SDK.... shouldn't it allow you to check that OpenCL checkbox?
Try installing it. Maybe using OpenCL fixes your problem.

I'll check this out. Thanks.

They are the same make, model and brand even. I use dual cards for gaming. There's no chance I'll be removing one of them.
 
Then you will have to endure the times they bug out, as the software base doesn't support multi card configurations.

And that is Adobe's fault.
 
Fair enough. Thanks for the help.

I looked at that AMD download for OpenCL. It was tested only through drivers 12.10, so I was nervous to mess with it as I'm on 13.x now.
