    Hello,

    I am experiencing a very weird issue in ARFoundation 4.0.0p3.

    See video here.

    I am using unity 2019.3.13f and I opened the ARFoundation samples master repo. I then installed URP, followed the instrauctions to setup the Forward Renderer and opened shader graph.

    I copied this shader from the shader graph sample library repo and applied it to an avatar in my scene. I haven't changed the shader at all.

    I then created an empty gameObject and added a Volume component to add the bloom fx. If the fx is active the issue appears, even if the colour properties in the shader are not HDR.

    Also, as soon as I disconnect the Normal Unpack node from the normal input on the PBR master, the problem goes away.

    The issue manifests itself on older Android devices, like a Pixel 1 for instance, on on iOS (tried iPhone XS and 7) but NOT on my Pixel 4 or my Pixel 3a..

    Can anybody tell me what's going on here???

    Many thanks

    Michele
