From: Petr Sebor Date: Mon, 11 Nov 2013 23:19:00 +0000 (-0700) Subject: meta: enable vertex attributes in the context of the newly created array object X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f2b844f59d86c5971118bfccb00ddc5a1b69797a;p=mesa.git meta: enable vertex attributes in the context of the newly created array object Otherwise, the function would enable generic vertex attributes 0 and 1 of the array object it does not own. This was causing crashes in Euro Truck Simulator 2, since the incorrectly enabled generic attribute 0 in the foreign context got precedence before vertex position attribute at later time, leading to NULL pointer dereference.
