In case you're not using xfdesktop to draw your desktop background then this is the same bug, the root pixmap isn't painted correctly by nouveau. So if my assumption that you're not using xfdesktop is correct, it is xfwm4 drawing the root pixmap in your case. But it doesn't matter really, because the nouveau driver is still the culprit.
