--- Comment #16 from Lemuel Simon <lemuelsimo...@protonmail.com> --- I am not sure if this was mentioned elsewhere, but I believe to problem is caused by a conflict between Night Color and 'Gamma Settings'. Night Color has worked consistently well for me (Plasma 5.24.1) until I open the 'Display Configuration' KCM in System Settings. Doing so would immediately 'reset' the display, getting rid of Night Color's red tint (while Night Color is still enabled.) Maybe that's why Night Color would 'disappear' shortly after activating at login, 'Gamma Settings/Display Configuration' gets triggered and fiddles with the gamma values. I have tested in X11, not sure how the Wayland session handles that.
