<![CDATA[Windows May 2020 (2004) Dimming no longer works]]>Flux v 4.115. Using the dimming shortcuts (Alt+PgUp/PgDown) Only dims the screen for a few seconds after the application starts. But anything more than a couple seconds after starting flux, and the screen no longer dims/brightens. Issue persists after restarts.

Do you have an automatic brightness feature on your machine?

In 4.116, we are adding an advanced option to use the "internal" color controls - previously we were forcing it on, but we're trying to stop doing that. So you can see if that fixes it....but mainly I would like to find out what is conflicting instead.

I do not. It's a desktop machine so f.lux is my only brightness control.

Just updated to 4.116 and flipped that option on, which seems to have fixed it 👍
