Second reply -- if anyone wants to run Dune3D, flatpak or compiled, they must set this flag in advance:
export GDK_DEBUG="gl-prefer-gl"
I discovered this while trying out the compiled version (it's essential for the program to run at all), and for some reason I thought the FlatPak install would have done away with this oddity.
Again, because my students aren't necessarily techies, this kind of hacking shouldn't exist in a program released to mere mortals.
But thanks again for alerting me to this release version.
