I've noticed that iPhoto's Edge Blur effect introduces some "blockyness" around the edges. It's very noticeable when viewing photos actual size, and becomes more pronounced upon repeated applications of the effect. It's almost like a mosaic, or stained glass effect. Interesting, but definitely not what you're looking for in a blur.
Any ideas as to what could be causing this? Is this usual behavior for iPhoto's filter that I simply never noticed before, or perhaps some issue with my photo prior to processing?
