Unlike X11, Wayland doesn’t allow to have a icon tray for some apps, such as amule. To get icon tray also for amule you can follow these steps:
- install
gir1.2-appindicator3-0.1(or something similar) [maybe not necessary] - try to start amule from terminal with :
GDK_BACKEND=x11 amule
If this trick works, you could use always it, modifying your .desktop file, with something like:
[Desktop Entry]
Type=Application
Name=amule
Exec=env GDK_BACKEND=x11 amule
Icon=amule
