Upgraded today from intrepid (graphics/compositing working fine under kwin) to jaunty.
Experienced the same kind of problem : sluggish. Kde even turned off the compositing itself after a few minutes.
Tried the old driver using this method : https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4
It did not improve the situation for me.

I'll try the UXA thing a little bit later.
