[Solved] Night Shift Switch is visible but doesn’t work

[Stinger22]

Hi @ALL,

my Night Shift mode is broken. I can turn it on in the settings, but when i do, the color dosn’t get warmer. Anyone got an idea of what the Problem is?
I’am using HDMI output of my RX580, Display was recognized correctly (not as TV), Integratet Graphic ist turned on in BIOS and configured as Headless (seems to worke fine)

Just to be clear... There is no difference in the color temperature between Night Shift turned on/off

SOLVED! Just did a fresh install (to Santa's NVMe), without any changes to config.
