Flux shuts off and comes back on randomly



  • I have it set to run all the time but it will randomly shut off when I am working. I will go in and adjust the settings/warmth and it sometimes fixes the problem but other times when I exit the preferences window it just goes back to a blue light. It started happening pretty recently so I downloaded the most recent update assuming it would help but it has not. Please help! My eyes hurt :(

    Hi @kelseapiquette can you tell me more about your operating system version and what kind of machine it's happening on? Does it only happen in one program? And do you happen to have automatic brightness enabled?



  • Hi @lorna, I have a 2013 Macbook Pro running OSX Yosemite 10.10.5. I have automatic brightness disabled. It happens mostly when I'm using Chrome but it isn't strictly happening there, that just also happens to be the program I use most.

    I think this build of Mac OS had a bug where the NVIDIA GPU would show a "washed out" color effect (which would look white) and the Intel GPU would display a "correct" color effect.

    You can test if this is true with gfxCardStatus: https://gfx.io/

    The only fixes are (a) locking to one GPU with the above utility and (b) upgrading macOS



  • That utility seemed to work, thanks @herf!
