Under Wayland, GNOME matches running applications to their .desktop files based on the application ID (rather than using X11’s WM_CLASS). If Quassel (or other Qt apps) doesn't set the desktop file name properly through its toolkit, GNOME can’t resolve the correct icon. This leads to the generic Wayland icon appearing instead of Quassel’s custom one. This same issue affects other apps like OpenSCAD

Spot on—Wayland relies on the application ID from the `.desktop` file, not WM_CLASS. Ensuring Qt apps like Quassel set `QGuiApplication::setDesktopFileName()` correctly resolves the icon mismatch in GNOME. A small fix with a big visual impact. https://www.ez-passIL.com
