It sounds like f.lux is crashing?

Can you look in Console for any f.lux crashes?

This should be the build you get from our main page, but it might not work on some browser configurations...?

here the picture links since embedding didn't work:

Also I haven't noticed the problem when playing a video file with VLC or similar -- just from streaming.

@Schnitte No, that's normal behavior for f.lux--it will only affect an active program (or in this case, to not affect it). Maybe this will be addressed in a future version.

Apple-support had no idea of this issue yesterday when I talked to them both in store (showing on mb12-demo computers) and via chat support. Im aiming for a mbp or a better brand next time :computer:

There were some automatic brightness bugs in Yosemite - you may have to reboot, or disable automatic brightness.

Update: It got up to 17 hours and I cancelled it. Any ideas of why this happened?

F.lux is not the problem, it's the display. You can easily have like 10 different displays in front of you (be it separate monitors or displays on tablets and laptops), and you can have 10 different results for color accuracy. Just because f.lux says it's at a certain color temperature, it doesn't mean that you're seeing exactly that color temperature. What you actually get is entire dependent on the display being used.

So, the only way to fix that is by making adjustments to the display's settings until you are satisfied with it. There's nothing you can do in f.lux, unless you wish to change the color temperature to compensate for the display's difference in color accuracy.

I would like to second this one but for a slightly different reason. Living in Alaska, during the winter the sun starts setting at around 4PM which isn't always optimal.

Since I use Plex Player a lot I'll have to wait for the next update that fixes the bug related to that before testing this.

@StevenCee I have had this problem for as long as flux has been around. I found that if I have it set to auto open on login, then I cannot have it also do the same thing with flux itself. Once I have it auto open at login, I can delete that and have it set to auto open within the app.

I also experienced that if I have it set to auto-open at login, I cannot get the prefs panel to appear from the many bar UNLESS I manually open Flux from the apps ƒ and then the menu pulldown works.

If I hav it auto open from within the app after having done the "dance" with auto-open at login, then th pull down menu for prefs works.

This "behavior" remains even with the latest beta version.
