Has anyone tried disabling the profile writer? Go to Terminal and type:

defaults write org.herf.Flux disableProfile 1

Then go to system prefs > displays and make sure to delete (or deselect) the f.lux profile if there is one.

I have this weird issue with f.lux and just one app (my IDE).
I recorded it in youtube video https://www.youtube.com/watch?v=l6HZXV3whCY

f.lux 42.1

Just updated to MacOS 12.6.1 but had this problem before; applied the fix and removed it via your instructions and voila -- everything works!


Thanks.

Use the keyboard shortcut Windows + A to open the Action Center, revealing a brightness slider at the bottom of the window. Moving the slider at the bottom of the Action Center left or right changes the brightness of your display.

Check if there is a logo on the right of your menu bar.

First guess is to check that Flux > disable menu options are not checked on. Could be disabled by app or by id. See this post for more details: https://forum.justgetflux.com/topic/7975/bug-apple-preview-turns-flux-off
