I can confirm this bug. Running Thinkpad X200 with Intel GMA X4500. For some reason the "Screen Resolution" app seems to think that I have three screens when I uncheck the mirror thingy.
As said above, when correct resolution (1280x800) is set, it draws the right pixels and such, but the "stretched" area on the right-bottom side has ugly artifacts with mostly black areas and a few colors.
