It has a virtual max resolution of the largest size square - this is to
allow for 90deg rotation. I'm not 100% sure where the extra 40 px came
from tho'! Perhaps you have a "Virtual 1440 1440" in your xorg.conf?

Actually looking below, output says your resolution is 1440x900 so maybe
your typing 1400x900 above is a typo above and that makes everything
fall into line as expected!

Don't think it the 1440x1440 thing is a problem TBH.
