I renamed .compiz with no effect, except on first reboot the boot stopped when it encountered the error given in bug #562843.
However, re-creating .config/gnome-session cured my problem with both window decoration and saving the Visual Effects setting. On first reboot, window decoration was there and Visual Effects were set to Normal. I set Visual Effects to None and rebooted. Window decoration was there and Visual Effects were still set to None.
