Christopher M. Penalver, it is not reproducible if removing the GNOME3 PPA which is what causes this bug to appear to begin with. Also, my machine requires those kernel prarameters to function correctly with the backlight, but removing them has no effect except inverting my backlight controls (0%=100%, etc.). That said, if one is to follow the workaround in comment #8 above, the problem does go away.

Therefore, I have reason to believe the shadow rendering bug is in xserver-xorg-video-intel in the repos being an old version. If one were to backport the newer version, I have reason to believe the bug will be fixed. This is why I initially filed the bug agains the GNOME3 PPA and then later xserver-xorg-video-intel and not xorg itself since it's a single package causing the bug.

I have not tested the newer xserver-xorg-video-intel driver in other DEs, but would be happy to do so.
