Public bug reported:
When using unity / compiz on top of llvmpipe and switching resolution
from something lower to 1600x1200 (This is a virtual machine, so this
happens regularly), compiz crashes.
Description: Ubuntu 14.04.1 LTS
Release: 14.04
libgl1-mesa-dri:
Installed: 10.1.3-0ubuntu0.1
Expected:
compiz shouldn't crash.
