Icon not associated with app windows on Wayland

Description:

In a Wayland session, the app icon is not associated with the app windows in the taskbar. You can add StartupWMClass= PPSSPPSDL/PPSSPPQt to the shortcuts, but as far as I understand, this will fix the problem only in gnome-shell. Or rename the shortcuts to PPSSPPSDL.desktop and PPSSPPQt.desktop to correctly display the icon in other DEs.

Additional info:

  • package version(s): ppsspp 1.18.1-3

Steps to reproduce:

  1. Login to Wayland session
  2. Run PPSSPP (SDL) or PPSSPP (Qt)
  3. look at the taskbar, there will be a generic icon instead of the PPSSPP icon
