Yup, still the same. Would also like to add that I am using Start10, and there's the option to blur the background and that works just fine. It's only the Fences background that won't blur anymore, all of a sudden.
Was the clean boot done under a new Windows Admin account?
Are you using Windows to apply the background? If so, are you using a slideshow? If you are, and do not use slideshow (just a static image), does it still happen?
