Title:
  GUI slows down significantly after random period of time.

Status in compiz package in Ubuntu:
  Confirmed

Bug description:
  Like a number of other users, I'm getting some variant of graphical
  slowdown after using my desktop PC for a random amount of time -
  between minutes and hours. I suspect the problem lies with compiz,
  OpenGL or graphics card drivers (NVidia in my case) as I have seen
  this behaviour with both Linux Mint 11 and 12 in the past, on the same
  PC. I don't believe there to be a hardware problem as this machine
  works perfectly fine running high-end games under Windows.

  Restarting or logging out and in often temporarily resolves the
  issue... but it eventually returns.
