If I understand correctly, glxspheres appears to be part of the bumblebee package (which we don't officially support here). Are you able to reproduce this bug using some other 3D app that we do support?
If not, another thing to check would be if the new mesa 8.0.3 fixes it, although I suspect it doesn't. I've set up a PPA for testing it here: https://launchpad.net/~bryce/+archive/mesa-803 ** Changed in: mesa (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/944627 Title: [regression] glxspheres runs very slowly in Precise (only 2-3 FPS) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/944627/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
