Comment 3 for bug 2023223

Finally, I got around to test it on a VM on Ubuntu 23.04. Indeed, sometimes the Diodoon icon does not show app on Ubuntu 23.04, and sometimes after waiting a long time it actually does.

When taking a look into the debug log (when running Diodon as G_MESSAGES_DEBUG=all diodon) the following message occurs:

libayatana-appindicator-WARNING **: Unable to connect to the Notification Watcher

So there seems to be an issue that libayantana which is the library we use for the application indicator, is not connecting to the appindicator extension.

This does not seem to be an issue directly related with Diodon but outside its scope, the Ubuntu AppIndicator and libayantana not playing nicely with one another.

Potentially those are the issues which could cause this:
