Hello! I have a strange behaviour of Icon-only task manager. I have few lauchers docked to it for a quick access (VLC, Chrome, Dolphin, Office, etc) and after finish working with some application (e.g. closing some office document) the docked laucher disappears. It is back there only if I Logout/Login again. This is on openSUSE Leap 42.2/Plasma 5.8.3 LTS/KDE Frameworks 5.26
