Has anyone else using a panp5 (system76 pangolin laptop, version 5) that upgraded to 12.10 find that some things, especially the dash, are noticeably laggier than in 12.04?

For me, just opening dash with hotkey, and searching for anything, are both slower. 12.04 was super fast. Even using unity tweaking apps to turn off background blurring and available app searching (and online lens searching), did not help...

Yes, I did reinstall the sys76 driver and restore system.

Partly due to this (but mostly that the philip5 ppa for digikam is not ready for quantal yet), I downgraded to 12.04 again...
