            Bug ID: 379196
           Summary: Dolphin does not appear on the screen
           Product: dolphin
           Version: 16.12.3
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-n...@kde.org
          Reporter: germano.massu...@gmail.com
  Target Milestone: ---

I am trying to use dolphin 16.12.3 but it does not appear on the screen, so you
get only a process running in background. I don't know at the moment if the bug
is reproducible, since it is the first time I experience it, and I am using
such Dolphin version since many days.
Plasma 5.9.4
