Bug description:
[ Impact ]
Upgrading Mutter 3.34.0 to 3.34.1 has broken Night Light and screen color
profile switching.
The commit at fault is 104bdde746c9ceccd9e9ab09b22ef228b8f7026e “kms: Predict
state changes when processing update” (which was intended to fix LP bug
1847044).
[ Test case ]
- From gnome-control-center display panel, enable the Night Light
- Force it on, and ensure that the display color temperature increases
[ Regression potential ]
Display gamma value might be incorrect
