From 7c16552f8dcc869b14cf7ef443a1b5de83b07973 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 30 Nov 2016 17:04:06 -0500 Subject: [PATCH] mesa: only verify that enabled arrays have backing buffers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We were previously also verifying that no backing buffers were available when an array wasn't enabled. This is has no basis in the spec, and it causes GLupeN64 to fail as a result.
