This is happening to me. Running Flux 39.983 on MacOS 10.12.6. Nightshift schedule set to "Off".

Screen darkens seemingly randomly even when Flux is stopped. If I turn Flux on and then Quit it, the screen brightens again for a few minutes, then darkens.

rebooting didn't help.

i reinstalled and it appears to be working normally now

@herf It's now there. Not sure why I wasn't seeing it before. Thanks a lot to all!

Can you post which version of macOS it is, and which GPU?

Hi sorry - when we fixed Norway we broke Singapore.

The new download (39.984) should fix both, I hope.

@nwalford That's how I did it. All there is in the preferences on my Linux version is latitude / longitude and 6 colour choices, can't automate colour changes over time of day etc. It's either on or off, so I found a place that suited what I wanted on the location setter and set it to that. I do like it, very restful on the eyes.

Use rainmeter app for customizing your desktop background and it has lots of cool skins.

We use the last piece of bundle name, because asking macOS for the full name uses 300% as much CPU.

I could probably fix this but that is the reason. :)

Have you tried "dim on disable"? It may help.

Regarding your question:

The system in the eye that adapts to color (and brightness) takes several minutes to adjust fully.

So one case for this feature is if you are using Photoshop and quickly responding to some IM messages or emails that come in. And basically you want to stay adapted to the "brighter" condition and not roll back and forth.

In this case, it turns out flipping between settings very quickly is incredibly disconcerting...the early prototypes were so bad I held back for a couple years on shipping the feature at all. (I thought the slower transition helped a lot!)

There is no good solution in f.lux right now for changing between white pages and dark ones, but it is important I agree. We have had prototypes of this for years but they basically involve hitting the GPU pretty hard to figure out what the screen contents currently are....impacts battery and overall performance, etc. (There are ways to do this but they are not exposed by the OS.)

Thanks, Colt1855

@lorna I have f.lux set to start on login, I use custom color settings, I have notifications and backwards alarm clock set, and no color effects selected. The other disable options work fine (for 1 hour, until sunrise, and for full-screen apps) - just the option to disable for specific apps doesn't work. That's a real problem for me because I discover that I have been editing photos with f.lux active, so the colors are wrong!
