@ManualControl I have also been wanting this for years. I am really getting annoyed by being blinded at random times in the morning. It should be easier to give manual control than to set up an automated system. It makes no sense.

It is only a text readout in the main interface. We are working on more things around it.

But for now, you just look at the solar time, and look at your normal clock, and think a bit about how they're different. :)

@herf I have prerolled the version of Nvidia but it seems to be the issue aswell. It seems like this happend of a update of WIndows and I am not able to reroll a windows version :( But it should be a bug that f.lux should be checking pretty soon because I guess lots of people do have this bug?

@mrelarsen said in Flickering at specific times:

Hi, f.lux starts to make my screen flicker every day at 21:00 and 7:00, Not sure why... the color goes from around 1936K to 1935K at that time if that helps in any way, it happens on both my laptop screen and my external monitor.
I usually just have to disconnect and reconnect my external monitor for it to work again.
If I do not have my external monitor connected it does not really flicker instead it switches to needing to be in focus, f.lux only works when focused on in the taskbar and the tint is removed when not focused.
I tried an experiment with an external monitor connected where I set the time to 20:59, f.lux then disappeared at 21:00 as expected and 3 minutes later at 21:03 the tint reappeared... 1931K

Turn off Windows Night Light.

Thanks for the hint !
Updated the NVidia drivers and that fixed the problem, along with many other odd flickering problems.

I thought I had updated my drivers recently by asking GeForce Experience to do it, but turns out it just triggered the driver download, waiting for a second confirmation to do the installation.

the Lenovo team kindly provided a work-around that stops the problem here.

so if anyone else struggles with this problem, give it a try.

OK so I've learnt the terminology I should have used was transitions, and I've figured out that it's only broken when they're set to Slow. When they're set to Medium they appear to work 100% of the time.

We do open each process one time (and close it) to find its filename for "disable by app". Do you happen to use that feature? We should not keep these handles open, but it's always possible that things get messed up.

If you're inclined, you could use Process Explorer to see what f.lux is doing:

@largo said in Mouse cursor:

Hi,

The bright mouse cursor is the result of applying f.lux colour filters? I really like it.
and what settings in the registry are we talking about?

No, the problem is due to the fact that the mouse cursor doesn’t change color. That is why it looks the way it does. You don’t need to edit the registry anymore because now you can just enable the option in the f.lux options called “software mouse cursor“.

The only problem with doing this and also with editing the registry to get the same result is, the mouse cursor can end up being invisible in some video games. So, for those games, you simply just turn off that setting.

We did add the "surface keys" option so that might work on some laptops.

The next version will likely have some interface for dimming more.

Driver Info

I do also have the same issue and as you can see. Almost that it turns out red instead. I hope there will be a fix anytime soon!

There are two things here:

We know it "mostly" works if you use Aero (desktop compositor), and not as well otherwise f.lux tries to disable when you use RDP (on the server side) to prevent double-applied effects, so this might get you.

Please try it and let us know what you find.

Interestingly, thanks a lot for making some points clear.

Hey I had tried this once before and it didn't work, but it works in the latest Windows. I will put that code back in. :)

This solved it! Thank you

I would like to take off from my list point number 4 after a day with f.lux. it seems perfectly okay.
