I have noticed that one some of my photos, that the initial display image seems sharper and clearer in Loupe view and then gets less clear after a few seconds when the image is loaded. I do notice that this occures mainly with images that have a high magnification (when using fit option). What I don't understand is why it would appear sharper and cleaner on initial load up view at the same display size and then get less clear. In most images the opposite occurs, it is a bit fuzzy to start with and after the full load and processing the image becomes clear. In some of these cases the opposite is happening.
Does anyone why this is occuring? and if so, can I fix it?
