+Subject: [PATCH] sna: Use VMask in 3DSTATE_PS
+Date: Wed, 5 Nov 2014 15:48:14 -0800
+Message-Id: <1415231294-12435-1-git-send-email-rodrigo.v...@intel.com>

+
+Using dispatch mask cause hangs waiting PS Done on some cases like bug #83207,
+with larger screen or when scaling it.
+
+Also mesa uses VMask instead of Dmask for 3DSTATE_PS because in some cases
+they were getting incorrect derivatives for subspans.
