Created attachment 102658 [details] A screenshot demonstrating the issue Sometimes (well, once so far), after the screen geometry changes (I moved from the laptop screen to an external screen), notifications show in the wrong place: they still use the old coordinates based on the screen geometry of the laptop screen. See attached screenshot. Unplugging and replugging the external screen fixed this.
This could be fixed with Plasma 5.8.4. Please add a comment when you updated to that version.
