Flashing Screen 10.11 El Capitan

 If you are getting flashing on any system, you should first update to the most recent version of f.lux. Next, turn off auto brightness in system preferences. A reboot is a good idea.

 I just want to chime in that I am on OSX 10.11.4 on a Mid 2012 Retina. I was getting flashing every second in Darkroom mode with auto brightness on or off, in a room with almost zero ambient light (baby sleeping) on Flux version 36.6. Downgrading to Flux 36.0 as suggested above has resolved my issue for now. I'm a programmer, and I'm happy to run nightlies, bisect code, install and uninstall things if you guys need help reproducing and figuring this out.

 @meckanical Where did you download it? Could you give me a link? 
- 
					
					
					
					
 @stek29 it's the link that @fluxydude added above: https://justgetflux.com/mac/Flux36.0.zip 
- 
					
					
					
					
 If you want to downgrade, please try version 36.5 rather than 36.0 - the link is https://justgetflux.com/mac/Flux36.5.zip - there are many bug fixes that you don't want to lose by going back to 36.0.... Please let me know how it goes.

 @lorna Thanks for that! 36.5 seems to be working just fine in Darkroom mode.

 For me 36.6 worked fine after upgrading to 11.11.4! (1 discrete GPU, auto backlight unavailable) 
 MacBook A1342 (mid-2010, "the white one")

 @stek29 Nah, stopped working after reboot 
- 
					
					
					
					
 @stek29 Oh no, can you tell me what happened after reboot? And does 36.5 work after reboot? 
- 
					
					
					
					
 @lorna 36.5 is ok 
 I'm not sure reboot is problem, 36.6 worked just after update, and in a few days I tried Darkroom -- same problem. So I just reverted to 36.5.

 @stek29 said: My macbook is mid-2010, so it doesn't have auto-brightness feature And this is still the same machine right?

 Just to chime in I am having issues with flashing on 36.6. Autobrightness off latest 10.11.4 update. Retina Macbook Pro 13" Late 2012. Downgrading to 36.5 to see if it fixes.

 @bleedblue12345 Just updating, no luck with 36.6 or 36.5. Had to uninstall.

 @OM44sound said: 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.
