<pre>I still find the reused Pixmap suspicious. It is only used in conjunction with
Present, so I can't see a reason for an extra refcount inside the Xserver, and
for mesa to reallocate the same buffer means it must have freed it and the
Pixmap.
I would be interested to see if:

I haven't seen that with a radeon hd7700/snb combo yet.</pre>
