Sometimes when i get an announcement at the bottom right of the screen or when i unlock my screen the popup will be left stuck at the top of that desktop (most annoying is the unlock session popup which blocks view from anything in the middle of the screen). Is this a known bug and/or what do you think could be done to remove these popups (my solution atm is logging out and logging in again and thus cleaning the desktop). I tried reloading the plasma desktop but that doesn't seem to have any effect on the popups. Help is appreciated
