Two images from a thread I started some time ago where other people confirmed the issue:

6970 here and had them from the start.

11.6 drivers installed and blue lines still exist :(:(

Aaaarrgh!! :(

:cry::cry::cry:

You forgot to add to the survey questions:

"I have an ATI card but I'm not experiencing the problem."

You have to be thorough in your sampling for a survey ;)

See question #2. This survey is specifically intended to provide AMD feedback regarding this error which apparently occurs exclusively on Cayman GPU's. The two respondents to question #3 did not leave an explanation, but I assume that they may be HD6990 users (also Cayman). The 6970m GPU is a Barts 6850.

The answer to your question is already there by implication :)

Yup I've had the blue line bug since upgrading to my HD6970. Didn't get it on my old HD4870 though. Screenshot attached.
