AMD drivers - Night Light

Not sure how many people this affected, but seemingly lots of Google hits out there.

Until the last AMD driver release - and for a number of years in fact - every time the display went to sleep, when it resumed Night Light settings would be ignored. Regardless of whether you used F.lux or Windows Night Light. The only way to fix was the Shift-Ctrl-Win-B driver reset hotkey.

It was always an AMD specific problem and despite a lot of bug submissions the problem was largely ignored.

In fact in the interim I began to wonder if my Dell monitor had developed a fault, or if I should buy a new DP cable (despite this one being VESA certified). I'd already changed the cable once.

Anyway, long story short, after the last major Radeon software update (a couple weeks back) the issue has been fixed. Hurrah! Two years or so of that bug and it turned out to be an AMD driver issue after all.

I guess I should thank them for belatedly fixing it.
 
Updated to the latest drivers and....

It's broken again :D Well done, AMD.

Not sure how something ostensibly this trivial can be a bug that runs for years and years and years.

I know, "first-world problems."
 
Well, burger me.

Brand new system with all new components. nVidia GPU.

You know what I'm going to say don't you... Same sodding issue with Night Light.

The only thing that hasn't changed is the monitor.

Given that not everybody using Night Light has this issue, I can only assume that the monitor must somehow be the cause of the issue. Have tried different cables so that can't be it.

I don't really understand how the monitor can be the issue. Or it's just a bug in Windows 10 with specific hardware. You can find bug reports at microsoft.com but they are yonks old with no resolution.

Oh well, new monitor coming soon. If it still does it then I'm going to cry.
 
@FoxEye I was just about to ask you to have a closer look at windows for being the culprit when I spotted your post #5. I hope you find the solution and if you do, please post it here. I don't know how many times it's been Windows being a **** when I've had problems related to the GPU.
