Duplicate of #3243.

In short: Wayland prevents global shortcuts as used by Mumble from working.
The linked issue does give a workaround for setting up at least PTT keys.

And according to my research so far there is just no way such global shortcuts can be created on Wayland. A bunch of other applications are affected as well.
