How are you setting the icon? Are you also setting the application name?

The reason I ask is because I encountered an issue with GTK applications
where the application name/ID needed to match the program name in order
for Wayland to match up the application with its icon.

However, maybe the problem is less extreme with Qt-based applications.
There is a guide about Wayland for KDE application developers and maybe
you will find this section useful:

Good luck!
