** Description changed:

  Over the span of 1-3 days I see my desktop consistently become more
  sluggish. The functions most affected are window movement, file
  movement, and sometimes window resizing. Other animations (such as
  minimizing fades, switching desktops, expo mode) are not affected when
  this degradation occurs. They remain smooth; however, I have let the
  problem go on as long as to find out that eventually all desktop
  animations/effects will degrade, it just takes a lot lot longer.
  
  I have recorded the output of 'ps auxw' and have slowly watched the VSZ
  and RSS memory columns creep upwards. A fresh compiz session will see
  675164 and 169860, respectively. After a day or two it will result in as
  high as 878552 and 255664. I have attached a log output from an hourly
  cron job (though I had suspended for a few days because of travel).
  
  After the degradation has occurred compiz will consistently use higher
  CPU. Dragging a terminal window while watching top: before: ~10%, after:
  ~30 percent.
  
  This has been an issue since 11.04 for me on both my Intel i915 and
  Nvidia machines (had an 8600 GT and upgraded to 560 GTX, both having the
  same issue). However, the nvidia machine is where it really hurts,
  _always_ happening within a day or two, while the i915 machine is pretty
  reliable overall with certain instances of degradation (used to be
  affected just as badly in 11.04).
  
  I will attach two videos demonstrating behavior before and after.
