From 0b70fc2db4555fb572fcb3695bf570f4720dbb81 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nicolai=20H=C3=A4hnle?= Date: Fri, 22 Apr 2016 13:46:13 -0500 Subject: [PATCH] radeonsi: only decompress the required ZS planes from si_blit MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This happens to "fix" a rendering bug in KotOR2, because it avoids a still not quite understood bug with MSAA fast stencil clear decompress. For the stencil clear bug, I have sent a piglit test (arb_texture_multisample-stencil-clear).
