Created attachment 468063 [details] Screen orientation changes causing UI issues in iOS 17 We are seeing a new issue in iOS 17 where requested constraints (width, height, aspect ratio) are being ignored. This happens in two scenarios: 1. On video stream initialization 2. On device orientation change The issue only affects the display in the UI. If you record video, the resulting file is not distorted. But if you do not handle iOS 17 specifically, code that used to work in iOS 16 results in a bad UI. See attached video as an example. It looks like the browser makes a copy of the track and changes its parameters at its discretion. It is possible to work around this in the UI, but some more info on whether this change in behavior was expected or a bug would be helpful.
