As I can see, LLVM 3.9 is quite young (September 2nd, 2016), that's
why Fedora 24 still doesn't have it in their stable package (and it's not
even in test in Bodhi). I'll try to compile my own LLVM as Edward advised.

I also tend to think it's on the window manager side, but it worked 20
minutes before and the only thing I changed is the GPU (and thus the gpu
drivers), that's why I thought it may have a link with the drivers more than
the WM. But maybe GNOME is using different GL extensions depending
on what the graphics card can do.
