Safari acting weird on hovered Portfolio elements

Hello !

I have been customizing the Portfolio listing elements by having round divs instead of squared ones. I’m using the zoom-in effect, and everything looks fine on every browser except safari on mac…

It seems the zoom-in effect make the image go out of the container, and the black overlay is also doing this (loosing the border-radius on hover).

I’ve tried several combinations, but can’t find anything to solve this.

Would you have any tips on solving that ? I’m counting on your css experience to help me with that…

Thanks a lot !
