    It seems like the Unity Developer who made the change into PostProcessing Stack on 2020 12-18 made a mistake.
    Its the commit for 3.02(aka 3.03 - - Fix FXAA when running on render-targets without alpha channel: force using green channel as luminance

    This makes a significant bug where it is creating weird artifacts on FXAA.

    Here is the project that you can download.

    Unity 2019.4.27f1 LTS, Built-in render pipeline.
    Post Processing 3.02~3.1.1 has this problem.
    Post Processing 3.01 and below(tested down to 2.3.0) which is before that commit, everything works fine.

    I need a higher version of the asset for PS5 support.

    Please fix this problem.
    Let me know if there is a better place to report this bug.
    This is a pretty critical problem for my project.
