I get what you mean, high reflection in small areas tend to do that, especially where there's a clash of colors, yea notice the fuzziness is all in the colored zones, it's still freakin good piece tho.
I think it has something to do with graphical output, it's kinda like the computer gets confused and just mashes things together, especially when a software blends too much color and reflection in a small area-more like a chaos theory enit- on the fixing part hm i don't know, but try blending less color in small areas.
now that you mention it, it does... never saw that. I try, even though using a mirror the placement and lighting are important, I like to have it as perfect as possible.. I am so anal with these at times.
