React + gsap = why render when cursor moves?

I made a custom cursor using gsap in react. I can’t understand why the rendering occurs when the cursor moves, although I don't change state?

👉SandBox

Thanks.

React Components by default don't skip render by shallow compare props and state, so every state update will trigger re-render.

You either need to implement shouldComponentUpdate, or extends PureComponent, or convert to Functional Component (which by default don't re-render if state doesn't change even if you call set state)
