+Subject: [PATCH 13/13] Implement triple buffering for wayland
+
+Change from double to triple buffering for wayland.  This enables higher frame rates without tearing artifacts by allowing both the glFinish and the buffer release interlock to operate without pushing the frame period to two vertical intervals
