This test should pass, when written as-is. I think you meant to add "#version 300 es" at the top? Or is this really meant to be based on the context? If so, can't you get a ES 3.0 context when requesting an ES 2.0 one? -ilia _______________________________________________ Piglit mailing list Piglit@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/piglit
