Public bug reported:
For the past few days both Unity 3d and gnome-shell performance has been
incredibly poor on precise. I suspect that the 3d drivers are to blame
because both of those desktops experience this poor performance but
unity-2d does not. Additionally the slowdowns happen during periods when
the 3d graphics are actively doing something (i.e. reavealing the Unity
launcher or moving a window in a composited environment), but when doing
something that does not require the 3d graphics such as typing this
comment there is no noticeable slowdown.
