      Also, you can shine your phone's flashlight at the screen and it should happen. More noticeable with f.lux at a night-time setting.

      What happens is that any change in ambient light causes the system to generate a new color profile (largely ignoring what is there). In my testing, even a custom profile (from an x-rite device) is overwritten, so it's not just a f.lux bug.

        @herf Still working without any issues. Just now tested with a flashlight on the TBD and the rMBP, both displays got bright and dimmed without issue. I'm currently in the nighttime mode.

        *Was I automatically updated to v36.3? Apparently this is the version I tested with. I didn't do a manual update. Still no issues either way.

          @jocamero yes it looks like Apple has fixed the issue and our workaround may be causing the problem. I'm going to post a beta right away to test.

            The main build on https://justgetflux.com/ is 36.6 and has the (old) fix.
            A reboot may be required to turn off the broken behavior!

              @justgetflux running 36.6 on OSX beta 10.11.3. No issues at all with automatic brightness. Seems to be resolved! woohoo

                @justgetflux Just updated and v36.6 also appears to be working correctly for me. I did the flashlight test without any issues.

                  Nevemind. I guess I spoke too soon... Flux disables when brightness changes with automatic brightness enabled. It was working fine before not sure what happened. Still on 36.6

                  Edit: rebooting seems to have resolved the issue. Why is this happening haha

                    Yea I've uninstalled flux until this issue is resolved. Doesn't help that I use an external monitor frequently too.

                      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

                                            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.
