Recently, @sean added a couple of links to the header, namely Website & Support DiS. When these links are visible, the icon doesn’t have enough space, so it displays in a shrunken version as you can see from this screenshot taken on my Android mobile phone.
Whilst there’s nothing functionally broken here, it does look a bit strange and is a newly introduced UX issue so I thought I’d mention it here in case it wasn’t known already.
I’d spotted this already so I’ve nothing to add to your issue @ma0sm but I thought I’d mention you’ve got a new podcast episode downloading and Google Photos wants to spam you with memories. x
