We support ARB_draw_buffers_blend, which introduces these functions but with an ARB suffix. But, if you read ARB_blend_func_extended, it talks abbout removing references to BlendFunci (not BlendFunciARB!) if you don't support ARB_draw_buffers_blend...which makes it sound like ARB_draw_buffers_blend should have introduced them. <a href="https://www.opengl.org/registry/specs/ARB/draw_buffers_blend.txt">https://www.opengl.org/registry/specs/ARB/draw_buffers_blend.txt</a> <a href="https://www.opengl.org/registry/specs/ARB/blend_func_extended.txt">https://www.opengl.org/registry/specs/ARB/blend_func_extended.txt</a> Since it's just accepting the core names in addition to the ARB names, which we're going to do eventually anyway, I'm in favor of taking your patch. I've seen a few of Intel's GL tests hit this bug as well.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
