SUMMARY When logging in, there is a smooth animation of the desktop appearing. This effect is enabled in KDE Plasma settings (Workspace Behavior -> Desktop Effects -> Login). However, there is no similar effect for logging out, when shutting down the computer the screen just abruptly turns black and that's it. I suggest adding a new effect that will do a smooth fading of the desktop to a black screen, I think it's easy enough. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10
