    This is how details rendering looks on terrains when motion vectors are enabled in the HD Render Pipeline Asset (motion blur has to be enabled as well to reproduce the bug):

    And this is how it should look (motion vectors disabled):

    The plants that are correct in both screenshots are rendered without the terrain details rendering system.
    Switching shaders to any of the build-in HDRP default shaders doesn't fix the issue.
    Disabling motion blur fixes the issue somewhat, however there is still some flickering on the AO-side-of-things as long as motion vectors are enabled.
    The render-issue does not happen in the scene-view.

    Unity version: 2023.1.0b12
    Renderpipeline: HDRP

    EDIT: Still broken in Unity 2023.1.0b13
