Citrix Fullscreen problems on KDE Plasma (5.16.x)

Using Citrix Workspace App (v1912) for Linux (with KDE Plasma 5.16.5) recently showed a problem with Fullscreen-mode – the Panel (Taskbar) was not recognied any more by Citrix-Apps and MSTSC in Fullscreen had a hidden Windows-Taskbar/Start-Menu.

I don’t know if the problem is related to any KDE/Plasma-Update, Worspace-App (Receiver Update),… but found a simple work-around:

  • Open Plasma Panel settings – More settings
  • Change visibility to „Windows can cover“
