[Sedat Dilek]

Hi,

I am testing mesa gles3 GIT (up to 8d27a9f) here on my Ubuntu/precise system.

Can you tell me what's going on or how to reveal why unity-3d fails
but ubuntu-2d gnome-session works fine?

I did also reset unity...

$ unity --reset

...which did not help!

NOTE: I am building here with LLVM/CLANG v3.2 if this matters!

My build-script is attached!
