I am the user from LRT3. I had upgrade to LRT5.0.7.

When I run Visual Preview,below the left-upper thumbnail can’t show percentage,it always show ~Visual Preview~, why?

In yours screenshots the visual previews are completed. The percentage will only be shown, when they are being generated, not when they are being loaded from the cache.
