Does anyone have a solution to this problem? Using Windows 10's Night Light is a workaround. But I would prefer to use flux, because flux is better than Windows 10's Night Light.

While inverting color selection the problem can be caused by magnifier and it can stop working. To make the magnifier work you just simply need to follow these 2 steps:
• Press Windows and + key to open magnifier tool
• Now, press CTRL + ALT + I key all together
• This will invert all the colors on the screen and magnifier will work properly.
Know more about inverted colors in Windows and make your system looks better than before.

The problem has been solved. Flux automatically starts up again every day. Had reinstalled everything and added an exclusion in defender, now it runs smoothly.
Thanks for the responses

Any ideas, anyone?

@herf Thank's for answer.

@TwoCables Thanks.

Hi,

I very much want this option, too. The biggest problem with the notifications is that they sometimes steal focus. This is especially annoying if f.lux is disabled for applications that prompt for a password on startup. You start typing the password and suddenly the focus is on the notification. So either fix the focus problem or allow to disable them at all.

Thanks

I solved it. The problem was not the f.lux itself, but in so called Pixel dot-inversion. I can't say i understood right how it works, but briefly all LCD monitors are flickering on some brightness\contrast values. For example my IIYAMA flickers like mad at 79 and 81 brightness but goes smooth at 80. When i acitvate f.lux i get flickering at 3450, and 3350, but 3400 is perfect. There are also some monitor settings that make your screen flicker.

There's a visual test for that http://www.techmind.org/lcd/dotinvrgb2lb.html and an article that explains all this. I finaly understood why i had everything back to shape when i did windows restore.

Took me some time to google all this out. Maybe this will help someone having the same problem.

@n8abx9 said in I am getting Windows 10 soon. How should I install f.lux?:

I would strongly caution against installing f.lux on Windows 10 at all. There are huge problems, dimming only ever kicks in AFTER log in, which makes it almost useless.

It’s been that way since the very beginning. It’s not specific to Windows 10.

It’s impossible to have f.lux start up before login. This is a limitation that has always existed in Windows, long before Windows 10.

@uiser356262 @kpoviv
It really does defeat the purpose of using F.lux in the first place, to keep your circadian rhythm in sync. But to answer the original question, you would just set the daytime, nighttime and bedtime sliders to the same level.

Click on the Flux icon in the taskbar

In the window that opens, click on little orange dot (or the three bars menu icon in the top left and choose Adjust day and night together)

In the 3 sliders that appear, set them all to the same level of your preference
