Flashing Screen 10.11 El Capitan



  • The only solution I've found so far is to downgrade to version 36.0, as @fluxydude said. The latest version doesn't fix the flashing, I also installed gfxCardStatus only to solve this, but nothing. Every time I went into Movie Mode, it started flashing and never stopped, only downgrading helped.



  • I'm using a Mac Mini 2012 2.5 Ghz, Core I-5. I'm wondering if perhaps a mac mini may not have a light sensor? Any other mac mini folks experiencing this flashing screen?



  • I started getting this problem. I have been finding that closing flux and then restarting it tends to make it go away for a few days.

    The interesting thing is that it's worked great on El Cap till quite recently.

    What gives? :P



  • Everyone experiencing this needs to 1. Make sure that 36.6 is installed (you might need to reinstall). If it doesn't fix your problem right away 2. Restart. If that still doesn't fix the problem, please 3. Let us know what your system is like and 4. disable autobrightness.



  • Strangely, I've never had any problems with f.lux and El Capitán, even with "adjust brightness automatically" turned on. However, last night I let OSX upgrade to 10,11,3 and this morning I'm flickering like a good 'un. So, it seems the latest OSX update has finally broken things for me too!

    I see I'm on f.lux 36,5 at the mo. So I'll upgrade and see if that fixes it. I've also disabled "adjust brightness automatically" for now, which does seem to have helped.



  • I just upgraded to El Capitan 10.11.13 and I am now having screen flashing issues. Installing Flux 36.4 did not fix the issue.



  • @lowi0008 what is your machine, have you rebooted? @madra too - have you rebooted? We cannot repeat this here after installing v36.6 and rebooting.



  • @lorna I thought I had rebooted but apparently had not. The reboot cleared things up. Thanks.

    I hadn't rebooted yet either. Seems to be working fine now, after rebooting –even with "adjust brightness automatically" turned on



  • @madra great to hear thank you!



  • @lorna i just uprade to v36.6 and rebooted like hour ago and no flickering so far!

    Thank you, guys for great work!!!



  • I reverted back to v36.5 which works fine without flashing on my old 15" MacBook Pro late 2008 Nvidia graphics. v36.6 starts flashing when setting f.lux in Movie mode only. Tried a reboot, but not disable "automatic brightness" and reboot together.



  • I have this problem too, but only when I enable dark room mode
    My macbook is mid-2010, so it doesn't have auto-brightness feature
    10.11.3 version is installed on it

    And I've found something interesting: it stops flashing when I open flux menu (screenshot)



  • I had / have this problem also. I installed the 36.6, turned on again auto brightness and rebooted (like two days ago).
    I've noticed some flashes from time to time, like for example at booting and if I change the light really really suddenly (i.e. I point my desk light directly to my mac screen, or if I'm in a room and I tilt my computer so the screen looks now somehow to the ceiling lights). Then, it occurs a flashing (just one), so it's is now really unnoticeable.

    I can live with it guys! Thanks for the update!

    PS/ It's also true that movie and dark room mode don't work properly. They flash or beats all the time, but I don't use those modes. I don't use my computer in a dark room (at the moment) and if I have to use the movie mode I use "disable for this app". Anyhow I encourage you to continue working on a solution for those problems and developing this wonderful app. It's great!



  • I confirm what @stek29 says. It stops beating when one opens the flux menu.

    It's incredible how weir sometimes software behaves.



  • @lpuerto can you tell me what Mac applications you're running when this happens to you?



  • @lorna puffffff....

    Mail, Safari, Evernote, Preview, Word, Pages, iTunes... for the movie mode Movist.

    I can try without any app if you want, and just after restart. (if you want) :)



  • @lorna I did it just without any app running after I reboot and the same result.

    Same problem for me: https://justgetflux.com/forum/topic/1967/manual-movie-mode

    Reverting back to 36.5 solved the issue



  • 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! :)



  • Hello everyone!
    I have experience flashing screen problem on my MacBook Air with 10.11 El Captain. I tried to downgrade to f.lux version 36.4 and still no luck. I love f.lux but the flashing problem really annoying me!



  • For me it happens when switching gpus on 10.11.3.



  • In Dark mode, it flashes every second.
    In Movie mode, it flashes every four seconds.
    When it auto dims at night, it very occasionally flashes.

    Flux 36.6
    OS X 10.11.3
    MacBook Pro (Retina, 15-inch, Early 2013)



  • My belief is that the issue is due to the os switching between the integrated and discrete GPU.

    One way to confirm this is to download gfxCardStatus - https://gfx.io/ and see if the flickering coincides with the switching of the GPU. This usually happens when the current process(es) increase GPU load dramatically, so you can sometimes see this when visiting a site with heavy flash adverts (usually newspapers) or when viewing Google maps as it uses OpenGL.



  • @neilb I have this problem on macbook which has only one GPU, so I don't think so



  • 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.

    Thanks for your post - if you want to try one more test of f.lux, a reboot may fix your trouble.

    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.



  • This post is deleted!


  • 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.
