SUMMARY If a modem is configured to automatically connect to the network at startup, no icon is shown on the panel for the nm-applet, only a gap is present in place of the icon, and on clicking on that gap the popup is shown as intended. If I disable or restart the modem, then the appropriate icon is displayed. Just no icon is displayed if the modem is already active at startup. STEPS TO REPRODUCE 1. Connect the PC to the internet. 2. Start up Plasma. 3. Notice that there is no icon at the place where the nm-applet should be displayed, instead, a gap is there. EXPECTED RESULT The icon should be visible during startup. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 20.04 (available in About System) KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8

Is this default Breeze plasma style? It looks it is a different style and that might be reason why the icon is missing.
Actually I seem to recall that was an issue in the system tray model itself which was fixed in Plasma 5.19. Unfortunately it could not be backported to 5.18 because the changes were too extensive.
