Here is my read only link
Test page called Safari-Glitch (live demo). I’ve added a page load animation to “preloader-div” element , it works great in Chrome, but I just checked in Safari and it is super choppy. Also the lottie animation inside “video-section” take three times longer to load than in Chrome.
When I delete video elements from video-section it is less choppy, but still not ideal. Something is super glitching in Safari…
