I wonder why there's such a blank area

[lzq]

I use this in react native,and this is my code.

const slider = useKeenSliderNative({ // loop: true, mode: 'free', slides: { number: list.length, spacing: 16 } })

And I have another question: I set 'loop' to true. When I draw a blank area, it will suddenly generate a rosette picture, this effect is very bad, how to solve it
