If you right click on the systray icon for f.lux, select disable, highlight disable, and you can have it disable for fullscreen apps, or by specific monitor. Either one may work for your gaming use case. I basically do the same thing.

Wow I have the same issue since I downloaded the last version, I find it incredible how easy it is to fix it then, I thought it was a software bug, thank you all the same.

@JimVardakis said in weird curve:

@TwoCables Thank you! That fixed it.
(so it wasn't normal after all)

You're welcome!

Is it possible that this could be a separate option/checkbox? This would be something I would be happy to beta test or something. I have this problem constantly and it can be really frustrating to have to make a minimum of 10 clicks (I counted) to cycle through turning the "Software mouse cursor" Off, then click done, then reopen and turn the "Software mouse cursor" back On.

Other suggestions to possibly help reduce the frustration is adding an "Apply" button that doesn't close the f.lux Options window, or a "cycle software mouse cursor" button or effect. Any of these would at least make it easier to manually fix the off/on process rather than having to program an auto-fix.

If you'd like a list of games that require this, I'd be happy to start keeping track and let you know, but it's probably 40% of the games I play.

Hi, can I use f.lux at dual monitors with help of Wireless HDMI? Plz need advice

The only way you can do it is by deleting a specific registry key. If you are comfortable doing that, then tell me and I will show you what you need to do.

For anyone interested, meanwhile I found a somewhat dinky solution.
This opens the app window and sends a close command to it.

In AHK:

Run, flux.exe DetectHiddenWindows, On SetTitleMatchMode, 2 WinWait, f.lux: WinClose, f.lux:

@JohnEdwa yes, this is really annoying. I've just uninstalled flux because of this. I want my smarttv (where i play games) not to be affected at all by flux. But for the moment I'll quit, I hope the dev will add this feature soon.

Had the same problem, tried everything I could from 1903 threads: install and uninstall countless times, update drivers, downgrade drivers, upgrade again, regedit cleaning, Fast Startup disabling, etc.

Eventually I tried uninstalling the Store app and then installing via executable --> immediately worked! Hope this solves your issue.
