@Adaolin Okay, so the funny thing is that when I activate or deactivate transparency it changes correctly.

So this is pre switching

This is when it switches due to "Use dark mode at sunset"

And this is after toggling the transparency effect

It seems like f.lux just does not force a reset or something?
Because the transparency does make the explorer window flicker once and resets the look.
Also, the way that it looks in the second picture does not take effect until I close the window and reopen a new instance.

This bug seems to fixed already. It's not reproducable for me at v4.111

@GreyName Me too. It's mind boggling how they just ignore it, or give the very lame excuse "We know better than you what's good for you". They obviously haven't been to parts of the world where it's sunny all night through in the summer and no sun at all whatsoever in the winter. Where tuning the light inside and on computer screens is the only option to normalize daytime hours and fight against winter depression and summer insomnia.

@kisaraksu It looks like your f.lux location is set to Australia. For example, 37.767,-122.497 is in Golden Gate Park, in San Francisco. Try clicking the arrow next to Location or enter your nearest major city.

Whoa. Nice find!! This is definitely better than ScreenBright. No, it's not just better, it destroys it.
