Hi, I have an app that uses ARKit with RealityKit using ARBodyTrackingConfiguration. I also perform CoreML detections on CVPixelBuffers from ARFrame. It worked perfectly without issues until around iOS 14.5. Since then if I run AR experience for longer than 20-30s with body detection and CoreML processing detections at the same time, I get big jump in CPU usage (from 80-100% to around 200-220%) which lasts for few seconds and produce lagging/stuttering video footage on device screen. I checked for memory leaks in instruments and can't find anything wrong there. If I disable either body detection or CoreML processing, the issue disappears. I even tried putting CoreML processing on .utility qos (which gives less detections per second) but it still didn't help. Here is the screenshot from Debug Navigator
