      This issue is always fixed by turning off the automatic brightness setting, but sometimes it takes a while.

      For some people (especially dual-monitor users), a reboot may be required after turning off automatic brightness.

        Thanks. It's working again without auto-brightness.

        I kinda liked auto-brightness but I guess I like flux more. :)

          I have followed the instructions but I'm still having this issue even after turning "Automatically adjust brightness" off. Rebooting doesn't seem to help either.
          I'v noticed that it only occurs when I navigate to finder, with Cmd+Tab or by clicking it on the dock. This happens even if no finder windows are open as long as the finder app is in focus.

          The screen never goes back to "sunset" mode while the finder window or application is in focus only once i move over to another application.

          Im running OSX 10.11.2 and f.lux 36.5

            Still having the issue - I'm not disabling automatic brightness. Fairly important feature for people who also care about the things that f.lux does. Are we pinning this on an Intel graphics card driver update (and saying that it's out of the hands of the f.lux folks)? I'd sure like to make this work the way it used to!

              @Ari-Brown There is no fix with automatic brightness enabled. Apple made changes that directly conflict with f.lux, and we have no way around it. For now you do have to pick one or the other.

                @f-lux-team FWIW, I didn't have any of these issues until I just recently upgraded from 35.4 to 35.6. Once I upgraded I had all the issues described in this thread and came looking for answers. I restored my 35.4 version from a Time Machine backup and things are back to normal. I have 'automatically adjust brightness' enabled on both screens. I'm using a mid 2014 rMBP (Intel Iris Pro Graphics + NVIDIA GeForce GT 750M w/ 2GB) connected to a 27" TBD. The flickering seemed to be an issue if I was using the Intel or NVIDIA graphics (aka using just the laptop's display or 2 displays). Currently running OS X 10.11.2

                  @jocamero Hi - this is interesting. We will test some more because our setup is very similar.

                  Is there any chance you restored any other files other than f.lux? Did you reboot after the restore?

                  Automatic brightness seems to be a little random with the Thunderbolt display, so the new El Capitan brightness feature may be "off" for some reason or another. We'll check it out.

                    @herf AFAIK I only restored the Flux app located in Applications. I didn't reboot. To clarify, I don't recall ever having any flickering issues with the TBD, only the rMBP's display. Both displays definitely have auto brightness enabled (very sunny in my office during the day and also work at night).

                    It also only seems to happen a few hours after sunset. Sunset is ~5pm, flickering started around 9pm-10pm the past couple of nights. I think this is when flux is fully enabled as apposed to partially changing the color temp around sunset.

                      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.
