Isn't this "boundary" the halo that USM is built upon? The idea of USM (and
this is way to short an explanation) is to introduce just such edge contrast
around and/or between objects and transition zones. The width of these halos
are controlled by the Radius slider in the USM dialog box. Try decreasing
your Radius substantially to see if that helps.
