Here's the bug I submitted back in June. No one looked at it. Unfortunately, in November I closed it as resolved because the pre-release xorg 6.9 appeared to have fixed it. It was really a binary compatibility problem (Aaron's patch I mentioned earlier) that was doing gray rendering in QT/KDE apps (but not GTK oddly). The bug has to be somewhere in this neighborhood.
I'll see if I can reopen it, or submit another.
