The shader cache doesn't upload the pre-compiled default programs at link time, so some batches may run with a smaller instruction cache size. As more programs are used, the instruction cache will grow, but something is not working properly with this on BSW. I found that if I disable the shader cache with MESA_GLSL_CACHE_DISABLE=1 but also set shader_precompile=false, then I also get the hang. (Thanks Ken for suggesting shader_precompile=false.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
