SL3 issue: "Zoom Picture" is adding a grey border around the image

Hello Bérengère,

Really sorry you've run into this issue. Our team is investigating the cause of the border/outline added to images, and we'll keep you posted on what we find out.

I'm curious to hear more about the magnifying glass icon moving when the file is published. Could you share a screenshot that compares what you see in Storyline versus what you see after the file is published? 

I'll be standing by!
