@herf i cant send screenshot but in win10 i can change intensity, if you right click on the night mode panel and go to settings, there will be a setting for the night light parameter right under the switch on and switch on night mode button.
@Jokester2101 You have the "hotkeys" checkbox off, so it should not affect the Windows key.
The only place we register a hotkey is related to this, and if f.lux is relaunched it does not even call the windows code to ask for the hotkey. It's specifically registering Windows+End.
@hehee we will look into it - this means that f.lux saw two different states in the hub, and to avoid a "race condition" where we fight another app, we are waiting for it to be stable before making changes. But as you say it would be annoying if it is always doing that.
@herf I did that and also updated my GPU drivers. Same issue only when using f.lux and rebooting. Perhaps it only affects certain hardware. I have a Surface Laptop Studio 2. Are there any logs I can provide you?
I have made a pretty big jump from Windows 7 to Windows 11 in last few months. On Windows 11 I am experiencing the same thing and it's killing my eyes. In my case, f.lux gets disabled once the system receives a notification which usually comes from Outlook in my case (new mail). After few seconds, the colors are back to yellow automatically, but this quick moment is enough to receive a deadly dose of the blue light in the evening, I have never experienced it working on Windows Vista & 7 for 15+ years.
@Burgerkrieg I think I figured it out, at least in my case. Checking "Always use Windows internal color table" fixed it for the misbehaving monitor, which was otherwise doing exactly what yours was.
@herf Yes, they support HDR. To be specific they are both an Acer Nitro 27".
Additionally, I am using Windows 11's Auto HDR setting. Which, to my understanding, changes a display to SDR if the content (or just games? That is all I see it with at least) does not support HDR.
This is especially blue but it is common to find the blue sky at 20,000-30,000K. CCT does go up dramatically as things get bluer, it's approximately 1/linear.
Most meters will only say CCT in a particular range (e.g., our measurement software goes to 100,000) - maybe the number is too large for this meter to report...
