[xorg-edgers][Unity 7 series]GPU lockup/Screen corruption on drag and drop in launcher

[Loris Zinsou]

My hardware is an Intel HD 3000/i7 GPU.

To reproduce this bug :
- you have to install the xorg edgers packages (mesa)
- you have to run Unity 7 series, either from staging PPA or Raring
- try repositioning an icon in Unity launcher by draging and dropping

Expected result :
- icon repositioning

Actual result :
- GPU lockup, screen corruption, display flickering
- killing Unity process doesn't work (corruption is persisting), you have to restart X.
