Public bug reported:
I rebooted into up to date trusty and noticed Unity was incredibly slow.
I hadn't rebooted in a while, so I'm not sure what package caused the
issue, though I'm guessing it is mesa (I saw i965 pci ids were ifdef'd
in the Launchpad diff, but I didn't look super closely).
~/.xsession-errors has this to say:
