Not resolved, so should still be listed.

Changes since last test:
KDE-Version += 0.0.1 == 4.6.3
Only changes color/form of visible corruption, does not change X11 hang

With 2.6.39.1, leaving fullscreen XV creates heavy corruption, closing
mplayer lets X11 hang. Machine still alive, can be remote rebooted,
this makes it to the logs:
[drm] nouveau 0000:01:00.0: PGRAPH - DATA_ERROR INVALID_VALUE
[drm] nouveau 0000:01:00.0: PGRAPH - DATA_ERROR

0x5039 mthd 0x0800 data 0x00000000
... (and so on)

With 3.0.0-rc2+ (git from hour ago), leaving fullscreen XV creates
heavy corruption, closing mplayer lets X11 "half-hang" (unusable, but
could switch to console, this is new), any other draw (opening the
KDE.Menu) lets it totally hang, machine still alive, could be remote
rebooted, this makes it to the logs:
