Flashing Screen 10.11 El Capitan

Tungsten_smooth

hi guys,
I've experienced same issues on my macbook pro retina late 2013. It only happened once i updated from mavericks to el capitan.
For me is only flashing white at rapid changes of light ( like 10 seconds sunlight bewteen clouds in Amsterdam :P ) . Also i've experienced flashing when switching (apple+tab) to Photoshop as i have flux disabled for white balance reasons. I'm with my auto brightness on and I didn't experience those flashes for a while. Only today i've updated my flux to last version so I'm looking forward for a fluxy time! :)

Have you disabled Mac OS X's new "automatic brightness"? This interferes with f.lux's controls as the autobrightness also affects gamma (similar to color) levels.

@fluxydude @jpalmieri I've a desktop, and whenever I try to move away from the screen, the camera (which doubles as a luminance sensor) notices this & the screen flickers. I suspect this to be totally an issue lying in between the camera/Auto-Adjust-Brightness & Graphics drivers in El Capitan.

despite claims here, this issue is not resolved. Still experiencing it here on OS X 10.11.4, with the typical symptom mentioned above--flashing on drastic light change, like when waking up from sleep.

@ariellangleyCB9 this sounds like you have autobrightness on maybe? As we have posted, there is no fix with autobrightness on yet.

Is the fix in development yet? Loving the app, but hate having to choose between auto brightness and f.lux - things that should really go hand in hand!

I only seem to be having issues when 'Preview' is in focus and open. This is with autobrightness off. F.Lux just seems to shut off in such cases.

For whatever it is worth, it only flickers for me when Preview is opened.

OSX 10.11.5 Macbook Pro Retina 13" 2012. Autobrightness off.

@bleedblue12345 Still no fix for this with the new beta.

@bleedblue12345 try the "ambientfix" pref and see if it helps.

@herf No luck unfortunately. Restarted my computer before testing.

Whenever I open something in preview f.lux turns off for the duration then turns back on when preview is closed. Interestingly it also turns back on if preview is not the primary application selected.

Thanks for the development! just donated.

Perhaps you have "disable for app" in the f.lux menu (f.lux -> disable) - if it is only happening for Preview, this is a likely reason...

@bleedblue12345 Well apparently I'm not too bright :D. Thanks that was the issue.

Maybe include a button to return all of those preferences to default? May be an issue for some other people as well.

herf

@bleedblue12345 yes we show a notification only the first time after you start f.lux, so if you miss it that one time, you'd miss it until you reboot. Maybe we need to change the icon or something for this.

bleedblue12345

I think I turned off the notifications because I disliked the "1 hour until sunset"... "2 hours until sunset"... etc

herf

options > backwards alarm clock for that.
But we apparently should put all this in one place. :)

My 5cents, disabling the auto brightness adjustment didn't help my issue.
What helped in my case is that I replaced the cable of the monitor.

lightning to D-SUB adapter with a D-SUB cable connected to the monitor -> constant screen refreshing waving/flickering effect (strangely only when flux enabled and color is warm)

HDMI -> DVI cable connected to the monitor - No flickering

I tried with 2 different monitors and I had the same issue / effect / resolution one LG and one Samsung. (Simply changing the D-SUB cable to another D-SUB didn't help, using another Lightning socket or adapter didn't help either)
