--- Comment #14 from Gert Wollny <gw.fossdev at gmail.com> ---
If by ESM error you refer to the overgright light blue artifact in the SPACE
RACESHIP scene, then is is a driver problem. If you run 

    R600_DEBUG=nosb blender 

it should go away. Unfortunately, things might run a bit slower like this, but
this optimizer (sb) is not completely reliable, so disabling it might be the
way to go. 

Using apitrace I've even be able to pinpoint one of the shaders where the
optimizer creates wrong code, unfortunately is is a shader that amounts to 15k
machine code instructions, and to find a the bug there will be very difficult.
