I have been trying to introduce Post Processing Stack effect depending on the user's actions. I import the Post Process package (2.12) via Package manager, add components to the AR Camera and when I build the tracking is not stable anymore. Please find screencapture with slight Chromatic Aberration. If I disable PP Layer and Volume components on the camera, tracking comes back to normal. I'm using Unity 2018.2.18f1 and ARFoundation preview 20. Has anyone encountered this issue? Thanks!
