@PingableUsername this is almost certainly Intel's DPST and not f.lux. See if your manufacturer provides a way to disable it.

We sometimes do disable it because it interacts badly with our more extreme settings, but we do not enable it.

Make sure you're using the latest version of f.lux. Sometimes, updates include bug fixes and better compatibility with newer operating systems like Windows 11.

@Capacitor-0 more fixes going up now in 4.128.

@illyn yes we overwrite that preset file from our online version periodically. Try making it read-only and see if it works.

@bakjoul We released 4.126 to beta track today - it should be more careful to avoid reading old state immediately after startup. If you can flip the backoff preference back on we'd love to know how it works.

@kenniky we have one other post today with a 2021 Intel driver (10th gen Intel) and the ".3448" update not working. Can you look for an update to the Intel UHD driver?

@santafedaisy can you post f.lux options > driver info?

@flux_user_55 Windows is reporting it "should" work, but clearly it isn't. Do you know if HDR is turned on? f.lux may not work with it.

Otherwise, the "9621" driver from 2021 for your GPU is pretty old, but it does seem to be the one Microsoft is still shipping - I wonder if they missed something. You can get an update directly from Intel, but usually for Surface it wouldn't be needed.

@santafedaisy Can you post f.lux options > driver info?

@aimmyarrowshigh We are not VMware experts, but you may wish to try updating the 2019 driver in particular.

@apollo606 Mine also I loved F.Lux in the past now with the Asus Pro Duo it only works for the Main Display. The one at the bottom does not work at all even after restart.
