On my laptop's built-in display, the extra effects work, but not on the external monitors.

@GoldenRelik you can post "f.lux options > driver info" and maybe email us a video from your phone? (support at justgetflux.com)

hi sorry, about half the posts here are spam so we had to do the manual filter. it's mainly me - will try to keep up to date.

@fluxie can you email us your profile (ICM)? support at justgetflux.com

@fluxie it is the main download now, we are slowly rolling the update.

Once you remove it, your laptop should go back to the regular color settings.

Same here~

@herf that didn't work. I don't use usb but thunderbolt.
However, an hour ago, I updated f.lux to version 4.131 (Jan 2024) and the issue is gone! I cross my fingers.

@RVogt222 if the location is right, you should check your timezone/system clock here:
https://justgetflux.com/timesync.html

Sometimes the timezone gets set to the wrong one, and so the displayed time "looks" right but it isn't really.

@Artsem-K

this can be done by setting the "late" slider all the way to the right, or by choosing the "classic f.lux" preset. only about 10-15% of Windows machines have a light sensor... if you mean to network the smartphone so it can be used as a "nearby" light sensor? then not really, it is too difficult to do things in the background on most of them

@Girofox123 thank you - it looks like the Windows API (called "SHQueryUserNotificationState") which tells us if it is a good time to notify someone actually writes to the registry, so we have stopped doing it so much (v4.131 should have the fix). There may still be a way to trigger this in the future, but it will be rare.

@anon_a_mouse Are you running the installer each time? f.lux should not do this more than one time.

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