[opensuse-kde] Leap 15.2 plasmashell login issues?

Hi there, are there known issues with Leap 15.2 and logging into a KDE session? When I login to a Plasma/KDE session I often do not get my wallpaper and no system tray. I then have to start yakuake and invoke plasmashell --replace & After doing that I get the complete desktop with system tray and wallpaper.... Any workaround known? Thanks!
