brent The above will work on Budgie, and any other affected desktop or window manager.
This happens because the notification is a part of gnome-settings-daemon, which will be activated if any application that leverages it is running. Unfortunately, the developers that implemented it didn't think to check what environment was running before sending the notification, as noted upstream in issues such as this one.
I appreciate what they're trying to do, but I wish they had thought this through a little more before shipping it.
