This is a bug in the Fall Creators Update. We posted a workaround/fix - make sure you're on the latest version (4.76).

Suppose you know we do this when an app is in the foreground.

People don't close things like Photoshop very often, so I am not sure we would add it globally...

@dango
How did you disable flux for the photo editing software? I don't any options like that.
I'd disable it when using photoshop and premiere pro.
Thanks for your help!

@herf oh, nice. thanx for help)

Turn off Windows Night Light

@herf said in Flux turns blue into purple:

@twocables It is possible to do much, much better. We have had prototypes and shaders to do this for many years. Some more is possible soon.

Right, but maintaining perfect color accuracy while using a very warm color temperature like 2300K or lower seems to be something that will always be impossible. Sure, it should be possible to get reasonably good color accuracy for casual use, but not for professional use where color accuracy is absolutely critical.

I wouldn't use it all night long, but during the day, it's likely pretty safe to use.

I think this feature request has a lot of weight towards it! I hope to see it in the future, only if possible though.

and you were using the suitable settings for flux?

We don't use MFC, that's probably about windows dialog boxes flickering when they redraw...

Settings are all stored in the registry - which settings are being reset?

Why are the energy settings not good enough for this? Do you want a better interface to change them?
