Hi,
Sorry, it’s an old thread and in German but I had the exact same issue. It happened also for few other applications, thus I dug a little and here is the fix: in the .desktop file, there is a missing parameter that tells the desktop manager the kind of windows associated.
To fix that (applicable to any other application that shows the issue):
- Launch PP
- Open a terminal
- Type: xprop WM_CLASS and enter
- A cross will appear, select the PP windows
- The terminal will give: WM_CLASS(STRING) = “Portfolio Performance”, “Portfolio Performance”
- In the .desktop file for PP, add that line: StartupWMClass=Portfolio Performance
Et voilà:
