"Based on your suse report, this isn't a keepassxc specific problem. There
isn't anything on the Linux side that would make our program invisible. The
only thing that would be similar is if you enabled:

    system tray icon
    minimize to system tray
    minimize on startup

And if the system tray was non existent. Proceed with the plasma debugging and
come back if there is a definitive lead to keepassxc code.

Also, we don't use KLocalizedString, that would be on the qt / plasma side.
Those strings are all standard button strings."

I would really need some assistance for the plasma debugging. The issue appears
even on a completely new installed device without previous user configs.
