I have noticed that the screen no longer fades to black when switching off after upgrading to 1903. There used to be a short fade effect when the screen turned off such as when putting the computer on sleep. The screen now just instantly goes off. I thought it was something to do with my laptop at first but it's the same thing on 3 different makes of laptop. They all used to fade to black but that now this no longer happens. Why has this effect been removed? Is it possible at all to bring the effect back?
