Since no one responded to Andrea's inquiry on 2015-01-17 and Ubuntu
12.10 is out of support, I'm going to surmise this was fixed somewhere
along the way.
If it still does occur, we can either reopen this bug or open a new one.

Title:
Unity in 12.10 becomes unusably slow after using Alt-Tab to switch
between programs (nvidia)
Status in Unity:
Fix Released
Status in unity package in Ubuntu:
Fix Released
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.
