Filter is disabled after toggling monitor DPMS

[pydronia]

After a hyprsunset profile is applied (or temperature set with hyprctl hyprsunset) and then monitor DPMS is toggled, either manually with the hyprctl dispatcher or with hypridle, on monitor wake the temperature is reset to the identity (i.e. no red filter). This doesn't occur if the monitor is powered on and off manually.

Apologies if this a configuration issue or if the issue is more relevant to Hyprland 🙇. I'm starting hyprsunset alongside other tools in my Hyprland configuration with exec-once = hyprpaper & hypridle & hyprsunset.

Having the same issue here. I end up having to pkill hyprsunset and hyprsunset & every time my screen turns off (also due to hypridle)

below patch to https://github.com/hyprwm/aquamarine (dependency of hyprland, so yes it's more of a hyprland issue) fixes it for me. Would appreciate it if somebody could get some form of it merged, don't feel I understand it enough to open an issue/PR myself. (My basic understanding is AQ_OUTPUT_STATE_CTM bit is cleared on commit & we need to set it again when modesetting after monitor toggle)

I think a one-liner like hyprwm/aquamarine#250 for hdr will fix it for ctm. will open a PR soon unless somebody beats me to it.
