I have a similar issue : vimeo video jerky but with a getUserMedia.

- On an iPhone with OS 14.5, go to https://codepen.io/sunlimet/pen/yLbgOEx
- Button share, then "Add to Home Screen"
- Open PWA, press play = video is lagging
- As you can see, there's only the Vimeo iframe and a navigator.mediaDevices.getUserMedia

Android do not have this issue, Chrome either.
Can reproduce on old IPhones (SE first and second generation, iPhone 6), but it's ok on iPhone 11

In Safari standalone (not PWA), it is better but it's also lagging
