--- Comment #16 from Rachel Greenham rachel@strangenoises.org --- It remains interesting (maybe) that you're having problems with 10.0.1 and I don't.
Looking at the commit, with an outside eye, it seems to be consolidating bits of code that were split out for different cards into a single implementation. So is it possible this bug actually arose some time back, only affecting a few cards (eg: yours) but after the consolidation it affects more cards (eg: now including mine too).
We're both south-islands hd7000-series cards, but not the exact same. Idunno, just my observations.
Can you take a video like the one I did (maybe just for consistency using the video sample I uploaded, linked in an earlier comment), so we can actually all see and confirm it's the same problem?
