The demo doesn't render correctly on Radeon 7870 (glamoregl+radeonsi) on Mesa 10.1. I didn't try Mesa 10.2 because of critical bug #65963, so others are welcome to validate on Mesa 10.2.
Rendered on my friend's blob: http://x.rushbase.net/62726ab9e439bc355ce7a4846ea1cafd67a5b628/glsl.mp4
How it looks for me: http://upload.nowaker.net/nwkr/1407613451_blah.png
I will soon check on Mesa 10.2.
Works fine for me in Iceweasel 31 on radeonsi from current Mesa Git master built against current LLVM trunk.
Thanks for the info Michel. I'll bump my drivers soon and let you know.
