=====I have found a solution to the screen flickering===== With chrome or opera, install the extension h264ify. This works for me to end the flickering. Not sure about Firefox. I had to register just for this post because it's so sad to see you guys flounder without a real solution. Best,

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.

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)

I just tested with different combinations. With only 3 monitors connected, I can't reproduce the artifacts at all.

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!

Thanks for this feedback @David-J.-Bookbinder - appreciate you taking the time to spell it out for me

@ersanzop how to resolve it.? . .

I stumbled upon this thread and noticed that it's quite old. Nonetheless, I'll try to help out with your issue. Have you tried updating your NVIDIA drivers to the latest version? That may solve the problem you're experiencing with the ""disable for fullscreen apps"" option. Additionally, you may want to check if there are any updates available for your monitor's drivers.

Sadly vers. 4.100 didn't do anything either ;-(

@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!

The issue with flickering when wake up the machine from Stand-by - issue still persists in even in the latest update. When the flashing happens there is a log: 2015-08-14 1:42:47.991 AM Flux[589]: Display list confused, doing full reset.

Hi, No artifacts so far, thank you. However when I put my laptop to sleep at deep night (1900K) and wake it up another day, I need to restart f.lux. It shows 6500K, however 1900K temperature is still applied. Closing f.lux does not fix it, I need to run it again. Not a big deal though. 4.118

Hello, I got some Yeelight Smart led Bulb 1s(color) Model YLDP13YL, I have f.lux and can someone help me how to connect this? I Have Lan option marked in yeelight app.

I am using macOS High Sierra 10.13.6 and it works just fine. My laptop is Macbook Pro 15" Late 2011 Hope this helps you or anyone else. Thanks f.lux, keep it up!

@lorna I would respectfully ask this stance be reconsidered. Working at night and trying to sleep with sunlight means a dynamic and chronically corrupted sleep cycle -- and since there is no consistent schedule, having full manual control is the only alternative.

I have the Philips Hue color lights and I'm very happy with them so I thought I'd share how I have them set up with F.lux on my Windows desktop computer and my Amazon Echo in the event anyone reading this might benefit from it. So I have the Philips Hue lights programmed to turn on automatically when the sun sets through an If This Then That recipe on www.IFTTT.com. The recipe works with the Weather Channel and it knows my location so once the sun sets, it then triggers the Philips Hue Channel to send instructions to my Philips Hue bridge, which turns on all the Philips Hue lights in my apartment. The color of the lights is the standard bright white that those lights emit if a color isn't chosen, but that's okay (for me) since it's just providing light when walking in the door. Once inside, though, I turn on my Windows desktop computer and F.lux overrides the system and changes the color of the lights to what can only be described as a soothing yellow/orange glow much like that soothing glow of a Himalayan salt lamp. (I have no idea how it does this, but I'm very happy with it and it's very relaxing. And it even dims as the night progresses.) The problem I encounter, though, is that I don't always have my computer on, so once the computer goes to sleep or turns off, the Hue lights then remain at that level of brightness until I change them or turn them off. It's not a big deal, but after reading this forum and learning that red light doesn't affect our circadian rhythm like blue and green does, I made another recipe on IFTTT recipe for a darkroom mode. The Amazon Alexa Channel listens for my trigger word, which is darkroom, and it instructs the Philips Hue Channel to change the color of all my lights to red. (The Philips Hue Channel allows you to name a color as well or use a CSS hex code. I tried a variety of them and settled on this one: #A00000.) So now, about an hour before going to bed I tell my Amazon Echo: "Alexa, trigger darkroom." And she changes all the lights to red. I feel the difference just like someone else mentioned here about how it made them feel and that's now my nightly routine. But hopefully, once F.lux becomes fully functional I won't have to do this and it will just take care of it all.
