I have a bit of an odd problem with an image I'm using in a UIButton backgroundImage property. As you can see from the picture, the foreground image (in an UIImageView) is much clearer, whereas the background one, is blurred and not as good looking - this is a image on a UIButton. 
Thoughts? Things to try? Any ideas would be appreciated. I'm doing this all in IB.
Retina and not retina file sizes were not exactly double. Keep your designers informed guys...
