<pre>It is the way of dumping that makes a difference. First and third dump below
are taken by mapping directly using brw_bo_map_gtt(). The second is taken using
intel_miptree_map() which does full batch buffer flush
(_intel_batchbuffer_flush()) before actually mapping the buffer:
6:10 r=40 g=12 b=0 a=255
6:10 r=12 g=0 b=40 a=255
6:10 r=12 g=0 b=40 a=255
In the normal run the batch buffer flush doesn't come between the writing blit
and the reading blit.</pre>
