+ [ Impact ]

  Since installing Ubuntu 24.04, every now and then Night Light gets stuck
  when my screen is locked at night and I unlock it in the morning. The
  screen is then very orange (more so than normally is the case with Night
  Light), and disabling it with the button in in the top bar menu does
  nothing.
  
  The only ways to restore the screen to normal are disabling and enabling
  the colour profile or running `gdbus call -e -o
  /org/gnome/SettingsDaemon/Color -d org.gnome.SettingsDaemon.Color -m
  org.gnome.SettingsDaemon.Color.NightLightPreview 1`
  
+ [ Test Plan ]
+ 
+ Unknown. Requires OP verification.
+ 
+ [ Where problems could occur ]
+ 
+ Night light and colour profiles are one in the same feature so touching
+ one always risks affecting the other. Since all such gamma changes get
+ committed to with other screen updates, there is the risk (particularly
+ with atomic mode setting) that a mistake in any one change will cause
+ the entire screen update to fail, resulting in black frames.
+ 
+ [ Other Info ]
+ 
  I have never been able to find anything remotely relevant in any system
  logs regarding this issue. It also does not happen every day, but
  probably once every seven to ten days or so.
  
  My PC has an AMD RX550 GPU using the amdgpu driver. I'm not sure if it
  makes a difference, but so far I've not seen this problem on my other
  machines with Intel IGPs.
