Night Colour is broken

[jansol]

Setting it to "always on" or triggering manually from the task bar does nothing.

X11 or Wayland? Seems fine for me on Wayland/AMD.

Wayland/AMD, was working fine in upstream nixpkgs.

Interesting. Anything in kwin logs?

[jansol]

Haven't spotted anything so far, no :(

Okay after a reboot it seems to somewhat work? But I did find a couple of interesting journal messages when opening the kcm:

Those are just the systemsettings page itself, and seemingly non-fatal. The actual night color-ing is done by KWin.

[jansol]

The systemsettings page seems to have trouble showing the actual configuration too, probably related to these errors. It always reverts the dropdown box to "Always off" even though it was set to something else. The "Apply" button matches what it's supposed to, though. Might be an upstream thing I guess.

Can't seem to repro this any more so I'll close this. Works nicely even with HDR enabled.

It does appear to be limited to only one monitor (and I have two) but from a quick glance that seems to be an upstream issue so I'll close this for now.
