CSS issue in night light color temperature slider
The color temperature slider modifies the default sizing from Adwaita. However, there is a bug that causes Adwaita's sizing to be used when fine adjusting the slider (i.e. long pressing or shift+click). This causes the window size to change.
Should be a rather simple fix to also override the relevant style to ensure the widgets size does not change suddenly.
