  [regression] unityshell makes compiz wake up 190 times per second on
  an idle desktop

  Expired
Status in Unity:

Status in “unity” package in Ubuntu:

Bug description:
  After I have opened and closed the dash, compiz (unityshell plugin)
  gets stuck in a loop and generates 190 wakeups/sec according to
  powertop:

  Summary: 277.9 wakeups/second,  0.1 GPU ops/seconds, 0.0 VFS ops/sec
  and 4.1% CPU use

                  Usage       Events/s    Category       Description
               1959 rpm                   Device         Laptop fan
               18.1 ms/s     190.0        Process        compiz

  This does not happen if I unload the unityshell plugin. Without Unity, compiz 
idles nicely.
