AR Camera feed jitters and shakes with mutithreaded rendering when running on iOS 16

Package: ARKit


1. What happened

The AR camera feed will start jittering and shaking when mutlithreaded rendering is enabled and the app is running on iOS 16.

2. How can we reproduce it using the example you attached

Build the player to an iPhone12 Pro Max running iOS 16, start the simple AR scene and scan around for a little bit generating planes. If the camera feed is still stable then go to the home screen and come back and the camera feed will go hey wire.

Reproduced on iPhone 11 and iPad Pro M1, however they for some reason need more geomtry in the scene before the camera feed starts to bug out.

    Don't really get where this issue is fixed and why it is marked as "fixed". If it's really fixed, what do I have to do to fix it for my project, too ?

    We encountered the same issue on iOS 16 beta 4. Jittering got better with beta 5 but still occurring. Is this known issue caused by Metal 3 update in iOS?
