This shouldn't be a problem and I don't see it myself, there is an
enblend --wrap option to deal with the case of a 360° panorama that
tiles horizontally, Hugin automatically sets this.
This sounds like a known Photoshop bug: if you scale an image in
Photoshop with an alpha channel, the edge pixels darken. The
workaround is to flatten the image before working on it.
