Summary Vimeo video jerky with getUserMedia

Vimeo video is jerky with 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

Thanks for filing, I am not able to reproduce this on the latest iOS 15 beta (19A5297e). Have you seen this issue on that build?

No, I haven't tried with the iOS 15 beta. I reproduce this issue on the latest 14.7. I made a video so you can see the issue: https://youtu.be/j3KQkExqBNI
