Can confirm the same issue still applies as of 2023.

f.lux version 4.124.0.0 1 Personal Edition

2x Acer Nitro VG280K 28" 4k 60Hz (8-bit RGB SDR)

I'm still having problems with the Darkroom mode....when I try to enable it, it immediately quits and returns to whatever the current F.lux setting is. I'm hoping there will be a Darkroom update soon.....

@eenoramic is it possible you were using our soft-dimming features before disabling? These are accessed via Alt+PgDn or Alt+PgUp, and we don't make them as prominent right now because they mostly appeal to desktop users and people who are sensitive to flicker on laptops.

@Alex5525 we do maintain three presets in this version - one for when the sun's up, another for the early evening, and another for right before bed. You can make the second two the same, just move the slider as you like.

@Alex5525 we are not seeing your screenshot. Can you try again to post it?

It seems like you may have a timezone or location issue - timezone is set by Windows and not f.lux.

To be sure your time settings are correct, check the webpage https://justgetflux.com/timesync.html

@itssfchris these settings are all in the "Disable" menu and it should be clear how to toggle them off once you find it!

@justsomebody for #2 yes we notice when timezones change and adjust things then, but this doesn't account for north-south travel.

We have done some tests with looking for changes to WiFi networks and the like, but it is a pretty noisy signal and so it requires us to chat with a server and becomes a privacy issue, so we have not shipped it, because we don't want to track anyone's location in detail.

@davidmorr yes I can tell that's hard to see. We'll work on contrast.

I guess there's a little romance in the NASA "Black Marble" image that we like, but you have to be able to see it. It looks like the pin is perhaps a bit big down there too.

@hooddy Chrome is kind of a special case because they install a system-level service to handle updates. Most apps do not have this kind of privilege.

As it is, we often need to make rapid updates when Windows or drivers change, so only our corporate build installs to Program Files.

@PingableUsername this is almost certainly Intel's DPST and not f.lux. See if your manufacturer provides a way to disable it.

We sometimes do disable it because it interacts badly with our more extreme settings, but we do not enable it.

@tellner have you tried the "far from the equator" preset? Agree that you should be able to set some more parameters here too.

Make sure you're using the latest version of f.lux. Sometimes, updates include bug fixes and better compatibility with newer operating systems like Windows 11.

I think at the moment Flux currently doesn't provide the option to override the time zone data for your location, but you can manually adjust your system time to match your current location's time while traveling.

@JorIS I would like to see this too. Mac OS does have Color Filters under System Settings>Accessibility>Display, then at the bottom, but that is a bit to dig though to get to it.

Would also just like to add that if you live in california a bedtime based on sunset and sunrise can make sense. It really really doesn't if you live in northern norway.
