Artifacts on calibrated monitor

  • Since I have a calibrated monitor, blue artifacts appear. For now, I had to move from f.lux to Iris, which works fine.
    Thanks for the great soft and I hope you can fix it quickly.


  • We definitely fixed a bug in this area for the v4.118 update - the latest Windows (19041) has a bug that interacted badly with f.lux. Were you using the latest f.lux version or an earlier one?

    Also, can you post f.lux options > driver info?

  • Similar issue on new Lenovo P15v. Windows 10 2004 Build 19041.746

  • Hi @meetloaf13 - can you make sure you're on the latest f.lux version?

    I think it should report the "fractional" windows build (like 19041.something) if you have v4.118, which is a clue that maybe yours is older.

  • @herf This sounds like the same problem I am having.

  • Our new beta (4.119) has a fix for rare X-rite profiles:
