A renderbuffer was the only way to get stencil because internally we use separate stencil on these GENs even for packed depth / stencil targets. _mesa_meta_bind_rb_as_tex_image would only generate those two targets. When support for GL_ARB_stencil_texturing was added for GEN8+, we had only one test in piglit. It didn't hit the non-GL_TEXTURE_2D* path, so nobody noticed.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
