If you want to get away from just Google, you can try iCloud or whatever Microsoft calls their Mail product now. If you want to get away with big tech run products, I recommend Proton. Of course you can always go full tinfoil hat and host your own email server with your own domain, but that will set you back at least 7 bucks a year, even if you for the cheapest register (Cloudflare, they don’t add their own fees at all, so you can’t really go lower).
Since this isn’t a GIF, I suppose this has something to do with eye movement, since it stabilizes when I zoom in on my phone or really focus on the center image.
