[Daniel van Vugt <daniel.van.vugt@xxxxxxxxxxxxx>]

This sounds like a regression of bug 930192. That bug is still fixed,
but overall rendering performance in Ubuntu 12.04 has regressed still
when using Unity. I believe this is a problem with the unityshell plugin
because performance becomes fast again if I (briefly) disable Unity.

In the mean time, please try this potential workaround:
1. Run ccsm
2. Go to Workarounds
3. Enable "Force full screen redraws (buffer swap) on repaint"

** Description changed:

- When "Sync to Vblank" is enabled in the OpenGL section of the
- CompizConfig Settings Manager (the default setting for precise)
- animations, specially minimize and maximize animations, aren't smooth
- and stutter a lot. Moving windows, or entering the Expo mode are smooth
- though.

+ ORIGINAL DESCRIPTION:
+ When "Sync to Vblank" is enabled in the OpenGL section of the CompizConfig Settings Manager (the default setting for precise) animations, specially minimize and maximize animations, aren't smooth and stutter a lot. Moving windows, or entering the Expo mode are smooth though.
  
  Disabling "Sync to Vblank" CompizConfig Settings Manager  solves the
  problem. However, glxgears still informs that it is "running
  synchronized to the vertical refresh" so I am not sure what the "Sync to
  Vblank" options actually does.
