Bild overflow hidden mit Code = geht
– CSS class zoom-image
– siehe Beschrieb unten

Please remove the Transform controls from the image module. Then please, apply an additional CSS class to the image module so we can catch it separately to not affect to all the other modules. 

Add the class zoom-image to it.

If you don’t quite understand what that means please refer to the following small tutorial:

https://intercom.help/elegantthemes/en/articles/2269805-how-to-add-additional-css-classes-to-divi-modules

Next, add the following code to the Custom CSS field under WP Dashboard / Theme Options / General Settings:

.zoom-image img {

    transform: scaleX(1.0) scaleY(1.0)!important;

    transition: ease 1s;

}

.zoom-image:hover img {

    transform: scaleX(1.14) scaleY(1.14)!important;

    transition: ease 1s;

}

Let me know if that works for you.
