The rest of your vision is at very low resolution, and it gets worse the further from the center it goes. You don't think so because our visual system does some crazy shit to fill in the blanks, but making a picture with limited information can't always be completely accurate. It's only usually pretty accurate for the typical things we look at.
Your pic is sort of like those adversarial images generated to trick some AI into believing a stop sign is a cat. It takes advantage of the flaws in our resolution compensating algorithm, which makes us think, at first, that there's different information around the edges depending on where we look. This also gives the illusion of movement, but it's truly our image processing which is moving things around. If you follow the lines within your foveal view, you'll see the truth. You can also stand back from the picture so the entire thing is in your fovea at once. Then it becomes completely clear.
