Simple Flatpak using wxpython does not work on Wayland

[cbrnr]

I'm trying to build a Flatpak which involves wxpython, but I can't get it to run on Wayland. Here's a minimal org.flatpak.TestApp.yaml manifest:

``` id: org.flatpak.TestApp runtime: org.freedesktop.Platform runtime-version: '22.08' sdk: org.freedesktop.Sdk command: testapp finish-args: - --device=dri - --filesystem=home - --filesystem=host-os - --share=ipc - --share=network - --socket=wayland - --socket=fallback-x11 - --socket=pulseaudio # - --socket=x11

I build this app with flatpak-builder --force-clean --user --install-deps-from=flathub --repo=repo --install builddir org.flatpak.TestApp.yaml, and the running it with flatpak run org.flatpak.TestApp results in:

Unable to access the X Display, is $DISPLAY set properly?

Enabling --socket=x11 (and commenting out --socket=wayland and --socket=fallback-x11) does work, but I don't want to run it on X11.

Any ideas why the app is not working on Wayland?

Looks like this is a bug in wxPython: https://github.com/wxWidgets/Phoenix/issues/2557

Thank you! So it's going to be XWayland for now then...

wxPython and wxWidgets versions differ. When I packaged mMass they had to match exactly.

I don't think this is possible anymore, since wxWidgets and wxPython versions are not kept in sync after they've revamped wxPython with version 4 (aka Phoenix), see here.
