I had the same problem as Kim (#84) - background displaced.
I had been using a proprietary nVidia graphics driver which was installed using Additional Drivers (jockey-gtk).
I removed/deactivated this driver, and restarted. The problem is gone.
I had also done 'sudo apt-get purge ubuntu-restricted-extras' and 'sudo apt-get autoremove' at the same time as removing the driver, so these may have contributed, but my guess is removing the proprietary driver was the difference.
My system is:
Ubuntu Oneiric beta (1 or 2?) with current updates
amd64
Intel NM10 chipset
Atom D525 processor
nVidia Next Generation Ion GPU
