Flashing Screen 10.11 El Capitan

Terence Yeong

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

lorna

@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!

lpuerto

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

It's incredible how weir sometimes software behaves.

lorna

@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
