I think this is the same thing that is affecting me. I have two monitors that I keep in sort of an "L" configuration (see screenshot for what the layout is supposed to look like, and what it ends up looking like when I try to actually set it up that way). The configuration worked fine in all previous versions of Ubuntu (all the way back to 8.10), but this upgrade messed it up; I have to disable the 2nd monitor entirely as I can never get it to display anything but garbage.
