Blurry Images of WebArchives in CoverFlow

I just noticed this in the last 24 hours- that the images rendered for CoverFlow (webarchives) are really blurry and pixilated - like a scale is happening-

I have resized the window - selected multiple groups- and previewed many archives- all are the same- really pixilated and blurry -

How can I fix this- PDF/Images and others are working fine- and I noticed that DevonAgent is also pixilated- but after what seems like a couple of minutes a few of them correct the quality (images) - but the others remain blurry and resized horribly…is there a solution?
