I've forwarded your bug upstream to https://bugs.freedesktop.org/show_bug.cgi?id=18163. Would you please subscribe to this bug in case they wish further information or need you to test something? Thanks ahead of time.
Also, I notice this chipset is sort of similar to one we recently put a fix in to correct dithering. Just in case that change may have caused a regression for you, would you mind testing the following "nodither" package, which has that fix disabled? If it solves the issue for you, we may need to disable that patch:
