      Reproduces reliably on Gnome Wayland session with Charm app:

      $ ./charmtimetracker 
The Wayland connection experienced a fatal error: Protocol error
Aborted (core dumped)

      See Charm's issue for the details:

      Presumably, problem is here:

      [4107857.686] -> xdg_toplevel@24.set_max_size](0, 206)

      Yeah, that's not a valid max size, Mutter is in the right - probably could be worked round here in charm, but we should fix that in the QtQPA
