I am implementing a card slide using Swiper, but during the card sliding process, the card intermittently appears to freeze. (mobile & web environment)

Regardless of the device, I want the card to slide smoothly without stopping when swiped. also, With the exception of the card at the very front, the cards stacked behind it should only have their background color(Here, it refers to the getBackgroundStyle function.) applied.

Occasionally, when moving a card using the mouse or touch and then releasing the mouse button (or lifting your finger), the card appears to freeze in place.

It is particularly severe when tested with developer tools enabled.

how do I fix?
