Desktop folder shows in different resolution than desktop itself

Description: Ubuntu oneiric (development branch)
Release: 11.10

Desktop folder shows in different resolution than desktop itself (as shown on screen).

Problem shows up after last Compiz update. Also after finding this problem I noticed that in Compiz properties - General settings - Output devices my display shows as 640x480+0+0
I tried to change it to actual resolution 1680x1050+0+0 but that was worthless.

Sorry for my english
