With `journalctl -r`, the only thing I get when the screen starts dimming and the nightlight is deactivated, is this line (username and machine name not shown):

When my display dims after X minutes of inactivity the night light function breaks which results in a much blue-er screen. When I move my mouse the dimming effect dissapears but and the temperature and brightness of my screen go back to the default value as if the night light function isn't on. Disabling and enabling the night light function fixes the issue until my screen dims again.
