    I tried fsr2 but it came with its own set of optione. Breaking some post processing, ghosting issues etc. FSR is perfect for our needs if only for the banding!

    Hi, I once met this issue and found that it's caused by upscaling. Maybe it's a precision issue in URP's FSR shader.

    Have you tried submitting a bug report?

    We did some digging and apparently it could be due to FSR causing the upscaling texture to become R10G10B10 instead of the default R11G11B10 Unity uses. I would imagine that's done on purpose.. but is likely the root cause.
