From fc3533c088d61888f5eae8e11fff2e1120d21777 Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Sat, 19 Mar 2016 19:57:00 +0100 Subject: [PATCH] radeonsi: Change default behaviour for undefined COLOR0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit d3d 9 needs COLOR0 to be 1.0 on all channels when undefined. 0.0 for the others is fine. GL behaviour is undefined.
