Created attachment 402540 [details] Comparison running on iOS 13 and 14. I just tested a web app with the brand new iOS 14 developer beta. The page transitions are noticeably slower then we are used to with iOS 13. See a repro app on https://ios-repro.web.app/list and the videos attached. The issue is similar but not exactly the same as a bug in iOS 13: https://bugs.webkit.org/show_bug.cgi?id=201048
