14.02 is the newest. I’m able to replicate the problem with Safari in Big Sur. And I don’t know what’s causing it. I’d have to dig around to see if I had any PNG files in a paid plan that had transparency and gets converted to WebP by Cloudflare.
UPDATE: I’m not able to replicate this on my own site with a transparent PNG converted to WebP by Cloudflare.
That might be a bug with the WebP conversion. I suggest you open a ticket and provide them a link to this thread. And post the Ticket Number here as well.
