    Hi I'm creating a sky shader for HDRP that has a moon disc as part of the shader (procedurally created). It looks great when static, but when the moon is moving the edges are flickering like AA is not being applied and I'm kind of stumped as to what is causing this?

    I have subpixel morphological AA active on the camera (SMAA) on highest quality. I've tried all combination of different Post AA options and nothing changes anything.

    Does anyone have any clue why this happens?

    I recorded the issue to show it:

    I think the only way to communicate such issues to UT is just post a bug.
