--- Comment #11 from Chris Wilson <chris at chris-wilson.co.uk> ---
My suspicion is that this is a missing render flush, since that is all the
effect the patch should have had (use existing render operations more often).

I've just pushed a patch to expose a debug variable in src/sna/gen7_render.c,
if you can please recompile the DDX with this little change:

diff --git a/src/sna/gen7_render.c b/src/sna/gen7_render.c
index ff2ddb7..244bf17 100644
--- a/src/sna/gen7_render.c
+++ b/src/sna/gen7_render.c
@@ -45,7 +45,7 @@
 #include "gen4_source.h"
 #include "gen4_vertex.h"

-#define ALWAYS_FLUSH 0
+#define ALWAYS_FLUSH 1

 #define NO_COMPOSITE 0
 #define NO_COMPOSITE_SPANS 0

that should test the simple flushing theory. (There are more complicated
flushing theories! ;-)
