From 1afe3359258a9e89b62c8638761f52d78f6d1cbc Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 20 Mar 2014 11:53:16 -0700 Subject: [PATCH] mesa: In core profile, refuse to draw unless a VAO is bound. Core profile requires a non-default VAO to be bound. Currently, calls to glVertexAttribPointer raise INVALID_OPERATION unless a VAO is bound, and we never actually get any vertex data set. Trying to draw without any vertex data can only cause problems. In i965, it causes a crash.
