Color banding when upgrading from 2020 to 2021

When we upgraded from Unity 2020 to 2021 we immediately got color banding issues. I looked through the migration guide but did not find anything in particular that would affect this.

I realize this is missing a lot of details about how our URP is setup, but since it just happened after the upgrade I’m guessing it’s something that changed between these versions that causes a common issue.

Since we didn’t actually change anything about the rendering I’m not sure where to even begin troubleshooting this.

We are using unlit.

A combination of organizing the cameras into a proper camera stack and activating dithering solved this.
