Okay, thanks for looking, I figured it was worth a shot. Would it be worth marking bug 9190 as blocked by this bug?
I don't know. Fixing this bug will not fix #9190, but enabling backbuffers (generally) enables showing further problems in #9190 (getting z-buffer via GetAttachedSurface). So feel free to do what you think is right :-)
