Carousel shows border on mobile

[Eeva]

Hi!

I have a problem on my mobile device (an iPhone 12 mini) using Safari. A very thin border is showing around a video on the first slide of a carousel. The border is not part of the video. Weirdly it's not showing when I do a screenshot or if I record the screen. So attached you'll find a picture of my phone.

The domain is: https://schoenetoene.ch

P.S.: I've tried all the things you recommend before posting to your forum.

@Eeva try this in custom css:

 video {
     -webkit-mask-image: -webkit-radial-gradient(white, black);
     -webkit-backface-visibility: hidden;
     -moz-backface-visibility: hidden;
 }
