Also our default settings do not trigger this - it is really only for extremely warm colors.

Though this does not happen much, only with late-night color, which is anyway not really suitable for gaming.

CPU rendering is very cheap thought, and performance impact is virtually non-existent.

so, make sure you disable the following setting in f.lux :
"Use GPU for better quality with very warm colors"
might need to play with "software mouse cursor when needed" on/off, depending on your setup. as having that option checked may introduce input lag and change mouse sensitivity for the worse.
