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?

lpuerto

@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) :)

lpuerto

@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?

meckanical

@stek29 it's the link that @fluxydude added above: https://justgetflux.com/mac/Flux36.0.zip

lorna

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.
