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.
