Could you explain the relationship to global shortcuts? That sounds to me like a bug which needs to be fixed in kglobalaccel

I don't really sure about this. So basically XlibNotifications uses XISelectEvent to monitor certain event. And strangely, the event is not received only if it is triggered by global hotkey.

Which "event"?

search XIPropertyEvent in xlibnotifications.cpp

For whatever reason, that part of code is not reached if it is triggered by global hotkey with current code, the display pointer is not shared with anyone.. I really don't understand why adding a new one helps, but it does help.
