Although not related to the issue, I see three problems with this PDF. 1) There is a improper ITXT key in the Page dictionary. Get rid of it or turn it into a proper second class prefixed key.
2) img0 doesn't belong and is wasting space. Since the data is in the SMask of the actual image, you don't need a separate resource - and in fact, optimizers would remove it since it's unused. 3) No Page transparency group, so blending is taking place in CMYK instead of RGB. As to the issue, you are running into the anti-aliasing algorithm conflicting with the transparency blending (partially related to #3). Don't use raster images if you don't need to, and watch the masks.
