Windows 10: Windows 10 - Night Light disabled after waking from Sleep Mode

This has been an on-going issue for some time.

Aster being in Sleep Mode, Night Light becomes disabled when the PC is woken up.

Obviously, this is when Night Light should be 'on'.

To re-enable I have to go into Settings, and System.

As soon as I select System, Night Light is re-enabled.


When will this be fixed?

Windows 10 1903 (may update) Breaks Night Light (built in night light mode)

Hi there,

I have 2 machines (1 was an upgrade install to 1903 the other was a clean install). Both nvidia cards, 1080ti and a 2080 in the other (1 has the latest nvidia drivers the other has the very last version prior to the latest). Both intel 8700k processors.

what is happening: i keep the night light mode always on, and prior to 1903 (when i was using 1809), when i play a game (full screen) the nightlight mode would turn off in game. when i alt tab to windows, night light was enabled. when i jumped back into
a game, it was disabled. no issues.

when i upgraded to 1903 (both the clean install machine and the upgrade), when i have night light on, and go in game and alt tab, the night light remains off in windows, this never happened in 1809.

not limited to games, but in both machines using 1903, sometimes when i start the computer, the night light mode is disabled. trying to turn it on does nothing, and rebooting fixes it. but if happens enough now where i suspect this is not a one off, and
the fact it happens on both my computers, and when i go back to 1809 there are no issues.

i also tried flux, but it did the same thing where it would sometimes when you turn on the computer be off, and no way to enable it without rebooting.

lastly, i noticed when the display goes to sleep (the monitor, not the computer), night light is disabled. You can turn it back on, but the monitor being put to sleep effectlivley disabled night light mode from running on 1903, but not on 1809.

somehow i think this is all connected, something in 1903 with night light mode is not working properly like it did in 1809.

computer stats:

Machine 1 (upgrade to 1903):

• 8700k
