=====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)

@herf Thank youuuu!!

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!

@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.

@waldyd Same "Display 1 has 0 size" problem for me on Ubuntu 18.04, on an old Thinkpad x230. Tried both of xflux11 and xflux12.

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!
