Xorg log file

I am running Kubuntu 12.04, and after upgrading to the packages in the 
xorg-edgers PPA, some OpenGL elements are no longer rendered correctly.  Among 
the package upgrades were:
 . xserver: 1.11.4 -> 1.12.1+git20120502+server-1.12-branch.ed33772a
 . xserver-xorg-video-intel: 2.19.0 (x-updates PPA) -> 
2.19.0+git20120501.7e09babb

The rendering bug can be seen with GLX-dock.  I have attached a
comparison screenshot where you can see the dock reflections are
incorrect. and the icon below the one with focus disappears.

Can we identify which package is the culprit? i.e. purge the ppa then
just install xserver-xorg-video-intel, then install libgl1-mesa-dri,
testing after each step to see when the bug is introduced.

The problem appeared when I upgraded libgl1-mesa-dri from 8.0.2 to
8.1~git20120501.2d75a1e2 from the xorg-edgers PPA.  I have reassigned
this bug to Mesa:Server/Ext/DRI.  Please reassign if this isn't correct.
