F7: Desktop Effects bug with nVidia GPU

[Clodoaldo]

Gnome desktop. Using nVidia MX 440 video card with the nVidia 96xx driver.

When I logout and login with Desktop Effects enabled applicattions
restart without the title bar.

To reproduce the bug:

Set the session to automaticaly save changes.
Open a terminal.
Open Desktop Effects.
Unselect "Windows Wobble when Moved".
Select "Workspaces on a Cube".
Enable Desktop Effects.
Logout and Login.

The terminal now starts without the title bar.
