Include the following details while filing a bug report (edit as applicable):

• Issue category: Multiplayer / Real-time Mapping-Depth /Example Package / VPS
• Device type & OS version: iPhone 11pro on iOS16.0.2, iPhone 8 on 15.3.1
• Host machine & OS version: MacOS
• Issue Environment : On Device
• Xcode version: 14
• ARDK version: 2.2.1 running on URP!
• Unity version:2021.3.9

Bug reproduction steps:
Using the PongHLAPIDemo demoscene configured with URP, and using the same build:

• on my iPhone 11pro with iOS16, the camera background video stutters strangely every now and again. Also sometimes, old video frames are display as if it goes back 1 second in time for a few frames. After 1-2 minutes the app crashes hard.
  Video:
  

• on my iPhone 8 with iOS15, this does not happen, it runs fine.
  Not sure what the problem is here…

This is a known issue that appeared with iOS16. We have a fix that will be shipped with ARDK 2.3 but in the meantime you can workaround it by disabling MultiThreading rendering in the Unity player settings.
