Gnome-Screensaver unlock: Dialog for password does not appear [Intel GMA 4500]

Bug Description

Occasionally the dialogue to type in the password does not appear. I can only see the wallpaper.

Workarounds:

1. switching between ttys back and forth until dialogue appears. I noticed, loging in to one of the ttys increases the change that the dialogue will appear when jumping back to tty7.

2. switch to a tty, login, and 'killall gnome-screensaver'

Sometimes - if I don't log out - it works perfectly for several days and dozens of locks/unlocks in a row. I do not have this issue on any other graphics card (e.g. Intel SandyBridge). How can I track down what is causing this issue?

System: Precise 64bit

lspci: VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
