Visual corruption when using Mesa 9 + unredirection in precise

[Michael Terry]

I was testing the unredirection compiz precise SRU on an Intel machine before Christmas. I got the same visual corruption issues that had been seen with the blacklisted Mesa 8. So we blacklisted Mesa 9 too. (I had installed Mesa 9 from the x-updates PPA.)

It is suspected that with the full LTS-Q stack, Mesa 9 will work again, and we can drop the blacklisting for Mesa 9 again. But that awaits verification.

Meanwhile, this is a bug to track the problem.

Steps to test the LTS-Q stack for any Intel user:

(amd64 or i386)
sudo apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal libgl1-mesa-dri-lts-quantal libegl1-mesa-drivers-lts-quantal

(amd64 with multi-arch requiring packages)
sudo apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal libgl1-mesa-dri-lts-quantal libegl1-mesa-drivers-lts-quantal libgl1-mesa-glx-lts-quantal:i386

Reboot, go to ccsm -> OpenGL -> Unredirect Driver Blacklist and remove the "9.0" or simply blank the option. Then try playing games et cetera.

We could now start considering re-allowing Mesa 9.0 as the supported 12.04.2 stack is in.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
