From 7caed50ff4224b0966bae7628cf99f8163cac4dc Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 12 Nov 2016 13:27:28 -0500 Subject: [PATCH] swr: disable blending for integer formats The EXT_texture_integer test says that blending and alphatest should all be disabled. st/mesa takes care of alphatest already. Fixes the ext_texture_integer-fbo-blending piglit test.
