Hello IPS Staff. I think you can change the "Google" icon to the one from Font-Awesome.

Font Awesome

Google has strict guidelines about how their logo shows on social sign in buttons, so we're following those guidelines - in the past some customers received automated warnings that they were not compliant.

Thanks. Good to know, I actually read and you are right Google requires it 😐

Crap, without bg, button looks more "cleaner"

I hate being a perfectionist 😛 

We all agree 😂 Unfortunately your mockup is pretty much exactly one of their "no, you can't do that" examples
