Hi, sorry for the long delay in replying…

I think I’ve found the situation. When the products are displayed in a carousel, inside the PICTURE element, above the IMG element comes two SOURCE elements, as seen in the screenshot. When I inspect the document, and remove this SOURCE element, the blur in the image disappears. I recorded a screen capture of what happens. Link below.

This happens in theme level or is the plugin used to generate the carousel? Can I disable it?
