That's pretty much expected when csmt is enabled. The more interesting
information in that log is "queue_id 1" (WINED3D_CS_QUEUE_MAP), which probably
means these are caused by wined3d_cs_map() and wined3d_cs_unmap().
(wined3d_cs_emit_update_sub_resource() is possible too, but less likely.)

This is an area that's known to have room for improvement. In some cases it may
be possible to avoid going through the CS for the map, in others it may be
possible to avoid mapping the resource at all.
