In your latest two updates there's an issue with the Image addon. Up until version 5.4.4 the border-radius was added to the img element.
In the latest two versions the border-radius is added to the .sppb-addon-single-image-container class which gets an inline overflow: hidden; style.
This messes up a lot of images when making the update from 5.4.4 to latest version, especially if you use images with position absolute.
Please add the border radius option to the img element back like it was.
