> It appears that the workload of low-level graphical operations used by
> compiz when, for example, moving windows has increased dramatically
> between Ubuntu 12.04 and Ubuntu 14.04.

> fallback when no GPU is available:
> How to reproduce:
> 1) Use the unity-3d desktop in Ubuntu 14.04 on top of a non-accelerating
> Xorg driver like "modesetting". Move windows around. Note peak and average
> How to verify compiz is the culprit:
> 1) copy /usr/bin/compiz from a Ubuntu 12.04 installation. Drop it in as
> /usr/bin/compiz on 14.04. Reboot. Perform the same window movement.
> CPU-usage should be substantially lower.
> This problem also affects VMs running on VMware ESX with a software-
