App crashes when rendering in 3D with wxPython inside a Flatpak

Python Help

I’m attempting to create a Flatpak from the Python-based Amulet Minecraft Map Editor. The Flatpak building is fine, and the app launches without an issue, but when loading a saved Minecraft world in the 3D editor, I get this:

INFO - PyMCTranslate Version 291
Gtk-Message: 13:20:08.646: Failed to load module "xapp-gtk3-module"
INFO - Loading level /home/evilsupahfly/.minecraft/saves/Otherwhere

The above exception was the direct cause of the following exception:

(amulet_map_editor:2): GLib-GObject-CRITICAL **: 13:20:40.497: ../gobject/gsignal.c:2778: instance '0x65340a9834c0' has no handler with id '3836'

It looks to me like there was some issue with wxPython creating the 3D map canvas, but I’ll be honest here - I have no idea what all this means, or even where to begin when trying to fix it.

Is this related to the Python project itself - some flaw in the Map Editor’s code? Or is this something that didn’t build properly in the Flatpak sandbox? How can I know which is which?

Unless some here knows the answer you need the wxPython folks to help you.

The wxPython folks where always helpful when I used to use wxPython.

I think you will need to join their user email list to ask questions.

Thanks! I’ll make a stop in their lobby next.
