I can't seem to reproduce this :s do you have any other reproducible scenario? I don't want to go as far as to blacklist this card.

I was testing the last good revision for about five minutes without any flicker, so the range should be good.

No, unfortunately not.

I don't know if this is a dupe of bug 1015718, as the flicker here is black for me, whereas the flicker in the other bug is white.

Because the temporary fix of bug 1015718 comment 23 also fixes this bug, I'll dupe this bug to the other.
