Some additional info:
I see two qualitatively different types of corruption: (A) dots, lines and
patches in random places; and (B) flickering lines across the screen. I don't
know if they have the same root cause or not. The screenshot from Jaunty has
both, and I still see both with 794ae743. That said, "B" manifests less
frequently (typically within a day or two, whereas "A" starts happening right
away), and when "B" does happen, a logout attempt causes X to freeze with 100%
CPU (logout works fine before then). Today when the B-type corruption
manifested, I captured a syslog with DRM debugging before and after a logout
attempt. The X freeze in response to logout seems to be the same problem as bug
23661. Attaching that syslog.
