Receiving Gdk error dispatching to Wayland display #128

Hi
When running modelio on Arch Linux with vulkan/wayland on nvidia I'm currently receiving a Gdk error:

Gdk-Message: 11:26:16.978: Error 71 (Protokollfehler) dispatching to Wayland display.

the modeler runtime is a separate installation in /opt and not modified in case of using shared ressources like an already installed java environment. All comes out of the sources from the modelio package.

Do you have any hints on this?
Best Alex
