Title:
  Unity in 12.10 becomes unusably slow after using Alt-Tab to switch
  between programs (nvidia)

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  Not sure what else to say. On my laptop with a clean 12.10
  installation everything works great. On my desktop with an Nvidia
  gts250 card (all available drivers in the repo) unity works fine, but
  after I use alt-tab to switch between applications, compiz memory
  usage rises (20, 50, 100mb, depends on... well, something?) and dash,
  all effects and even window dragging becomes unbearably slow.

  After I do a "unity --replace", everything is fine until I use alt-tab
  again. I can reproduce this as many times as I want.
