Comment 4 for bug 67163

Not as far as I know ; I installed the whole thing a few monthes ago but removed it all.

magnet@silmaril:~$ dpkg -l | grep -i compiz
magnet@silmaril:~$ dpkg -l | grep -i mesa
ii libgl1-mesa 6.5.1+cvs20060824 A free implementation of the OpenGL API -- G
ii libgl1-mesa-dri 6.5.1+cvs20060824 A free implementation of the OpenGL API -- D
ii libglu1-mesa 6.5.1+cvs20060824 The OpenGL utility library (GLU)
ii mesa-utils 6.5.1+cvs20060824 Miscellaneous Mesa GL utilities
ii xscreensaver-gl 4.23-4ubuntu8 GL(Mesa) screen hacks for xscreensaver
magnet@silmaril:~$

I don't see anything unofficial here, tell me if I'm wrong; anyway, should it halt the upgrade process? (I'm sure I could do it using apt-get just fine, I just think that the GUI util should handle things by itself).
