<pre>Ok, can you try
diff --git a/src/sna/sna_dri2.c b/src/sna/sna_dri2.c
index efc790f..3d3c50d 100644
--- a/src/sna/sna_dri2.c
+++ b/src/sna/sna_dri2.c
@@ -1485,6 +1485,8 @@ can_xchg(struct sna * sna,
WindowPtr win = (WindowPtr)draw;
PixmapPtr pixmap;
+ return false;
+
if (draw->type == DRAWABLE_PIXMAP)
return false;
to see if it using xchg swaps or if it is a side-effect of that patch on the
regular code that broke Mathematica?</pre>
