[EDIT/UPDATE]
Confirming it is the company's security software killing f.lux, nothing on f.lux's end. Appreciate your looking into it! This thread can be closed, or removed.

@Gonzalo hi Gonzalo - can you post in our Windows forum with f.lux options > driver info?

A bit more information

OK, I can understand why a two week delay works best for you, but now it's been over four weeks. I have 41.4 but heard that 41.5 is out now and it still tells me I 40.1 is latest. Are you still fighting with bugs in 41.x?

I had this issue too, unfortunately you cannot set your own sunset, or even better would be just pick times when you want the brightness to change! Only 3 changes would be fine like we have currently, but more would be great.

Anyways, I found a workaround that works for me. I have sensitive eyes so I like it to start getting dimmer as it is getting dark but not yet "sunset" and then even dimmer later.

I achieved this by setting the Bedtime color to be the highest at 5000K, then the Sunset to be "Incandescent" and the Daytime to be 3300K. Then I set my earliest wakeup time to 7:00 PM. By doing this I was able to adjust the graphs to something that works for me. You can set a slider to be higher than the slider above it by holding Control while you move it.

Just play around with it and I am sure you can find a setting that works for you!

Sorry to hear this - can you install again from the website?

catalina and 10.15.7

@herf said in Flux makes the screen more red while watching video on full-screen mode:

I suspect f.lux has detected that your machine has two GPUs and is trying to handle the switch between them using a modified color profile. I haven't seen this bug before, but macOS seems to be double-loading the profile sometimes.

The first thing to try is to disable our profile writer using the instructions here:
https://justgetflux.com/news/2014/10/28/profile.html

Do the "disableProfile" command and delete any f.lux profiles from your color settings.

Also which Mac is it?

MacBook Pro 13 2015 Retina; 2,7 GHz Dual-Core Intel Core ; 8 i5; 8 GB 1867 MHz DDR3

I don't have two GPU :)

There is a picture of the f.lux icon on this page:

If all else fails, you can also end the process from Activity Monitor.

Can we check your timezone?

Also what does it say at https://justgetflux.com/timesync.html

We posted a build (41.2) with a change to the way we sign the app. Seems to be working on 10.10.

Click on the f.lux icon in the menu bar

Hover cursor over "Disable"

Click on "when using Google Chrome"

You may consider a menu bar manager, I'm using Bartender.
On MacMenuBar.com there are a lot of menu bar managers.
With this tools you can hide menu bar items.
Usually these items are still accessible with a single click or keyboard shortcut.

Bartender 3 is for macOS Catalina, Mojave, High Sierra and Sierra.
Bartender 4 is for macOS Big Sur.

@herf -- I created an account just to say "THANK YOU" for this. It was driving me crazy (and I also can't believe I couldn't figure that out on my own...)

And thank you, @Dave_asprey, for asking the question \o/ \o/
