From 0b10ec1086d90de45ca2fab7b7b212508f50d1aa Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 17 Feb 2016 08:17:35 -0500 Subject: [PATCH] st/mesa: force depth mode to GL_RED for sized depth/stencil formats See commit 9db2098d for the i965 version of this. This fixes depth in a bunch of dEQP EXT_texture_border_clamp tests. And probably other ones as well.
