Hello,

I absolutely love f.lux - a highly useful app!

It still works in El Capitan but when changing the screen brightness using the keyboard the screen flickers between the screen temperature set by f.lux (warm) and the default screen temperature (cold).
When working at night this causes sudden blast of bright blue light and is very unpleasant on the eyes.

I'm assuming this is a bug? Has anyone else noticed this?

Thanks
 
Me too. Fortunately I'm using an external display, so it doesn't bother me much, but it's definitely noticeable and unpleasant.
 
I remember seeing somewhere on the internet that you can fix this by disabling "Ambient Light Compensation" in the Displays section of System prefs, but the option seems to have vanished... weird. Am I just going insane?
 
I'm on DP3 and "Ambient Light Compensation" is in the Displays, but only in the window for the builtin display, of course.
 
Same thing was happening to me, and the latest public beta update brought it back to normal.

I could never find the option in the display preferences. I'm guessing it is hardware specific and my mac doesn't have the necessary sensor?

Good to hear! Thanks.
