Images Blurry On Initial Page Load

Having the exact same issue described by the user Ben_langly in this post: https://community.shopify.com/topic/1374801

Looks like it was resolved but I’m using the theme “Dawn” and this is happening on any page that’s loaded for the first time. My home page features a print in the “featured collection” section and that’s what I want users to see first. Anyway, the image is always blurry on initial load and then sharp if I go to the product page. And then sharp again if I go BACK to the homepage.

Pretty sure I’m going to have to edit the code in this theme but not a coder and don’t want to mess up anything elsewhere. Can somebody please help me with this on the “Dawn” theme? Would really appreciate it as it’s driving me crazy and really want the images to be sharp everywhere, thanks. Website is: annehamiltonart.com
