In my case, the same phenomenon as above occurred in both versions 9 and 10 so that I did down grade to version 8. macOS Chrome and Safari, windows Chrome.

Is this trouble cause I'm using a CDN?

Same problem here. As a workaround the preloader-icon can be hidden with: swiper-slide::part(preloader) { display: none; }

same issue, a new preloader is added every time we loop through the list
