      Hello, I am having an issue with the black levels on my display when Flux is running on my Mac. When I quit Flux, the issue goes away. Here is my setup:

      • 13" MacBook Pro, 2018 running macOS 10.14.6
      • Dell 27U2720Q connected via USB-C
      • Flux version 40.1

      When Flux is running, the black levels on my display are "crushed" meaning the levels between the darkest blacks are impossible to see. Here is a good page which describes limited vs full range RGB signals and here is a good test pattern to test the issue. When Flux is running, even during the day when no color change is being applied, the top row of blacks all blend into the background but if I quit Flux, the squares become visible.

      Is this a known issue? Any suggestions on how to fix this?

      Thanks,

      Scott

        We had an earlier workaround that may have affected you. Try the "delete" command here and see if it helps:

          Ah, I remember having the Cyan issue a long time ago. I ran the delete command and that seems to have fixed this. Thank you!!!
