Hello, Catholicans,
It is no theme bug but the default functionality of WPBakery. You are editing Home page right now, so we can’t do tests there, but with our demo image on our test site the hover zoom works fine – https://gyazo.com/af858f5f173adddf800bebb1e6afa436 , here is the size of image https://prnt.sc/frrUuOugyd0z and layout structure – https://prnt.sc/-0jBkNPDmIa1 Depending on your desired result, you can use other elements of WPBakery, or even enable Massive Addons plugin and use more elements, for example – https://massive.mpcthemes.net/single-image/
Kind Regards, 8theme team
