What is your system theme? 

Is it Plasma's? That is expected to happen because the Plasma / KDE theme is 
provided by a plugin installed by Plasma itself, which an AppImage Qt will not 
be able to find or load.

Is it Gtk3? The qgtk3 plugin would need to be supplied in the AppImage, which 
could trigger including of the Gtk libraries in the AppImage too. But if you 
have a Gtk-based environment, without the plugin, Qt should fall back to the 
"GNOME" theme, which does not link to the Gtk libraries (yeah, naming is 
upside down) and simply tries to emulate the Adwaita L&F.

I don't think you can get a good L&F integration with an AppImage, period. We 
can only get a good approximation, with either the "GNOME" or "Fusion" styles.
