@Alex5525 we do maintain three presets in this version - one for when the sun's up, another for the early evening, and another for right before bed. You can make the second two the same, just move the slider as you like.
@justsomebody for #2 yes we notice when timezones change and adjust things then, but this doesn't account for north-south travel.
We have done some tests with looking for changes to WiFi networks and the like, but it is a pretty noisy signal and so it requires us to chat with a server and becomes a privacy issue, so we have not shipped it, because we don't want to track anyone's location in detail.
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.
@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.
@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.
