Hello everyone. I have exact same problem and just like the previous reply I also have NEVER USED f.lux, don't have it installed on my macbook and never had. Has anyone figured out a fix for this issue?? I'm running High Sierra 10.13.5, Safari 11.1.1, and Intel HD Graphics 4000, and I have had this problem since El Capitan. Thank you all in advance,

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!

My setup is a 4 screen configuration with one screen without a monitor attached. The screen is an Elgato HD60S device which captures HDMI video and outputs to USB 3.0 and passes through to monitor. However, I do not have a monitor attached to it. I view the screen using video capturing software like OBS Studio. I do not want to apply flux to this display as its only used as a virtual display only for recording and streaming to YouTube.

@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!
