Apitrace of the demo

This demo requires GLSL 430, so it will only works with mesa git on evergreen.
I have this crash with REDWOOD and JUNIPER chips. 

The demo works fine on others drivers (tested on radeonsi and intel).

I've got this while debugging with GDB:
"Thread 1 "Sample_Tutorial" received signal SIGSEGV, Segmentation fault.
r600_decompress_color_images (rctx=rctx@entry=0x7c82b0, 
    images=images@entry=0x7c92b0) at r600_blit.c:420
420                     r600_blit_decompress_color(&rctx->b.b, tex,"

I've attached an apitrace. The crash occurs at frame 0, call 2983.

The other Ogre UAV demo (TutorialUAV02), does not have this problem.
