f.lux Not Using Default Windows Color Profile During Daytime

  • In f.lux version on Windows 10 build 1809, f.lux is not using my Windows color settings. The problem occurs on two different monitors.

    Steps to Reproduce:

    1. Start f.lux during the day
    2. Get an ICM file
    3. Apply the ICM file as the default for your user account in Windows Color Management

    Expected Result:
    Different colors

    Actual Result:
    No change.

    I would upload a profile but the forum says "You do not have enough privileges for this action."

  • We stopped looking for changes to color profiles frequently, due to a major memory leak in Windows May 2019 update. If you change color profiles, you now have to restart f.lux (or wait an entire day for us to check).
