Hi guys

I'm having a very frustrating issue.

So I'm developing a site and the site icon has a transparent background.

It's displaying in Google browsers just fine.

However in the browser I'm using, Vivaldi, it's showing up with a white background.

I don't think this is an issue with Vivaldi, however, as other sites have icons with transparent backgrounds that display just fine, including this site when I was using a temporary site icon.

Anyone have any idea why this might be happening?
