@rebsurazal look for the icon at the top of the screen:

I've upgraded to macOS 12.3.1 which is supposed to fix external display issues and while my issues aren't 100% resolved, this particular issue I was having with the flickering which occurred when f.lux was adjusting the color temperature has gone away, so I think this is resolved and was a macOS issue which was conflicting with f.lux.

@fulminare Did you find a solution yet? I am having very similar issues and just posted about it here:

@herf Great, thanks.

Everyone who can, please update to Monterey 12.3 and install this new build:

@fluxter The problem might have to be fixed by DisplayLink.

The suggestion is 5 (!) years old. Hope we'll see some progress on this soon!

@zendude

me too

@f-luxuser

I have the same problem with DisplayLink.
Have you found a solution yet?

Ok, thanks for the explanation!

Blue light and UV are different - LED-backlit monitors do not produce any UV.

We design f.lux to work with daily rhythms, so if you have normal vision, you need some blue light during the day, and much less at night.

@paulschreiber this issue has been there since forever. Reported on it way back. Unfortunately, it's still present.
