Ok, a workaround seems to be setting the saturation to 100%, it seems
any addon that modifies the saturation causes the CPU to spike.

** Description changed:

- When using the Dim Inactive function in Compiz, it takes about 80% CPU
- usage, causing the fans on my laptop to run constantly whenever this is
- enabled.
+ When using any addon that desaturates windows in Compiz, it takes about
+ 80% CPU usage, causing the fans on my laptop to run constantly whenever
+ this is enabled.
  
  I will attach screenshots below.
  
  Steps to Reproduce:
  Enable Dim Inactive in ccsm
  Open two windows, monitor cpu usage
  Use keyboard shortcut to toggle dimming on and off
  
  Compiz-Plugins version 1:0.9.8.6-0ubuntu1 from synaptic
  
  Graphics Card:
  Dual Graphics (AMD Radeon)
  00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI BeaverCreek [Mobility Radeon HD 6620G]
  01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Whistler [AMD Radeon HD 6600M Series]
  
  Video Driver: fglrx-updates
  
  Distribution: 12.10 Ubuntu
  
  Configuration in GConf

** Summary changed:

+ High CPU usage when using any addon which desaturates windows
