I do have one issue, but I don't know if it's related to the theme not being native 1080p or due to the videodriver or something. In the scrolling text areas e.g. in My Movies (imdb info) there's some 'pixelation'. Between the lines, I see random white dots, which shouldn't be there. It's not really bothersome, but I was wondering if other (1080p) users have this issue too.
Could be that you didnt install the GeoSansLight font or you did after you started MP. Try clearing the skin cache and see again.
