Created attachment 102988 [details] plasma--shell 5.8.4 - early notifications persist after Splash Screen When I start up Plasma 5 now - I often get a notification that my: "Touchpad was disabled because a mouse was plugged in" during the Splash Screen initialisation process. As expected... However with plasma-shell 5.8.4 this notification will just stay hanging at the top of the screen - in front of all other windows. Even restarting both Kwin and Plasmashell does not completely remove this popup window... I still see a persist outline of the popup notification. It also survives suspend-resume cycles...
What you are seeing is a fallback notification that only appears when no notification server is running. What likely happened is that the notification got sent before the relevant part of Plasma was started and then it got stuck there. We have since reworked the handling of this special case so it shouldn't be an issue any more
