This bug may be "fixed" in quantal, but it is most definitely /not/ fix
released in 12.04, the LTS release.
I use 12.04 on an intel IVB laptop at work and have been patiently
waiting for a fix for 12.04 to be released for 6 months now. My laptop
works fine for a week or so, and then randomly the unity icons disappear
and I need to reboot to get them back. According to comment #28 , I can
downgrade mesa to 8.0.2 from main (instead of updates) and it will work
again, but then I'm not getting mesa updates (which assumedly helps for
intel IVB graphics, especially with docking/undocking stability, iirc).
The current mesa version installed on 12.04 (from updates) is below, and
exhibits this behavior:
$ dpkg-query -l | grep libgl1-mesa-dri
ii libgl1-mesa-dri 8.0.4-0ubuntu0.2
free implementation of the OpenGL API -- DRI modules
ii libgl1-mesa-dri:i386 8.0.4-0ubuntu0.2
free implementation of the OpenGL API -- DRI modules
$ apt-cache showpkg libgl1-mesa-dri

Is there a way to mark this package as fixed for quantal but not for
precise? Or is the official answer for LTS support is to upgrade to
12.10, which isn't LTS?, or run another desktop shell?. This is a rather
big black eye for ubuntu when I try to convince others to use it..
Or am I completely missing something, which is always a possibility...
