Would this be the one in images/menu.svg that gets mapped to :/icons/menu.svg
in the raphodo/resources.qrc resources file?

Is it the theme, or is it a problem with SVG rendering? Do any of the PNG
images in the resources file appear?

It looks like you use your own icons instead of those from the system's theme
so maybe it's not theme-related. You would have to try different themes in
Pop! OS to check whether a more mainstream Qt theme works properly.
