Works for me on ivb with master. Created attachment 70048 [details]
output
It still happens on ivybridge and sandybridge.
I've posted a patch to fix this on mesa-dev: http://lists.freedesktop.org/archives/mesa-dev/2013-January/032425.html Fixed on master branch by commit 8c80bdc4a8d0b1c39cad8b8bfb1b982a498f0a8e. Still fail on 9.0 branch. commit 8c80bdc4a8d0b1c39cad8b8bfb1b982a498f0a8e Author: Kenneth Graunke Date: Tue Jan 8 17:00:13 2013 -0800 i965: Move program_id to intel_screen instead of brw_context. According to bug #54524, I regressed oglconform's multicontext test when I reenabled the fragment shader precompile. Closing. This was fixed on master a long time ago. Verified.Fixed. |

Precompiling the shader at link time often allows us to avoid compiling it at the first use. This moves the expensive compilation and optimization process to game or level load time, rather than at draw time, where we really can't avoid any cycles and don't want to risk stalling the GPU.
