For the record... everybody tends to get the Wayland platform plugin warning. I'm using Cinnamon X11 and I still get it.
The AppImage currently checks what desktop is being used (via xdg) and sets QT_QPA_PLATFORMTHEME TO gtk3 if the DE is Gnome or xfce. It seems to be theming pretty well on Gnome, Cinnamon, Plasma/KDE. So if you're using something different setting your own QT_QPA_PLATFORMTHEME is definitely the way to go. The Qt xcb platform is definitely distributed with the AppImage (in fact it's the only platform plugin) So I'm not entirely sure why you had the specify QT_QPA_PLATFORM. I'll look into it.
