@herf I have prerolled the version of Nvidia but it seems to be the issue aswell. It seems like this happend of a update of WIndows and I am not able to reroll a windows version :( But it should be a bug that f.lux should be checking pretty soon because I guess lots of people do have this bug?

@guillaume1978 this is because the dock does not provide traditional color controls, so f.lux has to emulate them using the GPU.

If the dock happens to be a DisplayLink one, you can sometimes add these controls back using the registry: https://support.displaylink.com/knowledgebase/articles/1886413-how-to-enable-night-light-or-f-lux-on-displaylink
