A performance fix, just make sure that icon movement is fast.
[Regression Potential]
Visual regressions, shell drawing problems. Big change, many regression
potentials.
Original description:
Description: Ubuntu 11.10 / 3.0.0-12-generic #20-Ubuntu
Quadro NVS 290 - Dual screen
Display is too slow to be usable. Moving windows or icon is sluggish.
Switching from Nouveau to Nvidia proprietary driver helps a bit but the issue
is the same.
I found 2 ways to "fix" this issue:
* disabling Ubuntu Unity Plugin in CompizConfig Setting Manager
* disabling one screen
Disabling "Sync to VBlank" doesn't help
Upgrading the nvidia driver with ppa:ubuntu-x-swat doesn't help
