Interesting - this is the "certificate revocation list" from Comodo. This is the "browser" (here the internet explorer code we use to check for updates) making sure our SSL certficate has not been revoked.

Usually this bandwidth cost would be "shared" among multiple apps/websites, but in this case, f.lux made the first SSL request with this registrar, so IE pulled the CRL down also.

v3.17 should not be updating (that is the setup3 link).

However, if you had another version that had downloaded an installer, 3.17 would run it on relaunch.

Can you try these steps?

Uninstall f.lux Install setup3

@tungsten_smooth Thank you very much for your help :)

This is usually Intel's DSPT ("Display power saving technology") and it's a video driver update, not f.lux that's doing it.

DSPT is getting harder to disable, but look for the Intel HD Graphics Control Panel, and some reddit posts have registry hacks to turn it off too.

Glad you spotted the potential culprit ! Thanks for your careful work ;)

I was going to say that I agree with christian but instead I do think twocables is absolutely correct. 1900K is more than enough if you really think about it.

@thenrich you can update by hand:

It is probably already paired. Does it affect your lights or show a "Hue lights to use" in the menu?

If you're inclined to debug it, I highly recommend Fiddler: https://www.telerik.com/fiddler

No, we added the new hotkey and took it out of the dimming mode (because they are really different features).

There is no difference - they are both entirely red.
