Set the Wayland app id late enough for it to take

Browse Source

The launcher and the task bar have shown a generic tile for a working
window since the call was written. set_xdg_app_id sat at the top of
run(), on the reasoning that the app id is read when the surface is
created — true, and beside the point: the call goes through Slint's
global context, and there is no global context until something installs
a platform. That is BackendSelector inside shared_gpu, or AppWindow::new
falling back to the default, and both happen further down. Called before
either, it returned NoPlatform and did nothing at all.

It moves to just after the window is constructed, which is not the same
as shown — run() is far below — so there is a platform to talk to and
the surface does not exist yet.

The failure was logged at debug, which is why a year of grey squares went
unremarked: the whole symptom is invisible from inside the application.
It is a warning now, naming the consequence.
