Hey everyone. So I have exact same problem like everybody else here, except I NEVER USED f.lux and I don't have it installed on my macbook and never had. However I have adjusted my color temperature to 8000K, I believe the default color scheme (Color LCD) uses 6500K colour temperature. I'm pretty sure this problem is caused by Intel graphics driver, because if you go to the Chrome settings and disable "hardware acceleration" the issue is gone. Not sure if there is a way to disable hardware acceleration for safari... Im on El Capitan 10.11.6. Firefox works fine with no problems.

Flux 4.33 beta, windows 7 x64. Can't get tray icon to front. "Control Panel\All Control Panel Items\Notification Area Icons" - show all icons is unchecked. When I set "Show icon and notifications" for flux, every time computer is restarted there is new entry for flux and tray icon is hidden. I removed /nohide from executable but this brings flux window to front, not tray icon.

here the picture links since embedding didn't work: https://www.dropbox.com/s/f1mu1azacaohefp/Screenshot 2017-02-21 23.30.39.png?dl=0 https://www.dropbox.com/s/x3cyex5yr50e0ry/Screenshot 2017-02-21 23.32.06.png?dl=0 Also I haven't noticed the problem when playing a video file with VLC or similar -- just from streaming.

My 5cents, disabling the auto brightness adjustment didn't help my issue. What helped in my case is that I replaced the cable of the monitor. lightning to D-SUB adapter with a D-SUB cable connected to the monitor -> constant screen refreshing waving/flickering effect (strangely only when flux enabled and color is warm) HDMI -> DVI cable connected to the monitor - No flickering I tried with 2 different monitors and I had the same issue / effect / resolution one LG and one Samsung. (Simply changing the D-SUB cable to another D-SUB didn't help, using another Lightning socket or adapter didn't help either)

Had a crash this morning. Machine was up, I could SSH to it, but the screen was dark and flickering. Rebooted and checked the system.log. This may be a GPU failure issue, but I figured I would throw this in for those with similar errors and a LOT of Flux messages, but the more I dug the more it seemed like the issue was my GPU and not Flux.

Wait and see FTW!

@herf Did not know that was an option, thanks!

@Tungsten_smooth said: @Gentz Now you can open the magnifier and invert the colors (ctrl alt i). I think it's the APU not understanding the color inversion part. Yeah, something somewhere is definitely not allowing f.lux to work correctly. :/

Thank you Elhem! I will give that a shot.

I am working to the the xflux12 version working under Linux Mint 18.3. Found the original xflux, put xflux12 in the same location, then ran it from console so I could see what happened. Went simple and just gave it my zip code, left everything else default. I believe I am running X, don't remember how to tell (it's been a while since I poked my Linux install). I got the following output, which seems to indicate xflux12 thinks it is working, but then something goes wrong. Now what? https://pastebin.com/m6TAHuCz

@TwoCables said in UWP f.lux: Also, as you can see from the update page, it says "These pages are popping up too early for Windows App Store users. Sorry, we’re working on a fix!" Sorry, I totally missed that! It's good information to know! I will probably just stick to Windows App in this case since developers know about the issue :-) Thank you for the very quick reply!
