Comment 10 for bug 869196

I'm facing this problem too. My problem is not with menu of applications, but with the menu/icons in right corner.
My setup is a dual-monitor and a gt 240. I'm using nvidia proprietary driver.
The problem seems random .. sometimes this bug happen in left monitor, sometimes in right monitor.

I followed the instructions given by Martin Pitt and installed the unity/oneiric-proposed but that not worked for me.
The problem still occurs.
