Hmmm... that's the CB_SIZE which is 64K max, aka 0x10000. Somehow it's trying
to write to 0x24000 which is well past that. Should probably throw some asserts
in to see where it's happening.

IIRC I fixed some issues with CB writes at some point, can you confirm that
this happens on a semi-recent mesa? Preferably Mesa 11-rcN or git?

This happens on mesa git (3c6c4d4f298ec81fe57992790a68aaab2e573519).

cb management patch

This is a very preliminary patch, but in replaying the above trace, I get the
same results as on intel (at least on the last frame). And at least with mesa
10.6.3, I do see the same blurriness as you did. (Fun, looks like it makes use
of GL_DEPTH_BOUNDS_TEST_EXT, which wasn't available in 10.6.3.)

Please confirm that the included patch fixes the blurriness. It's a
pile-o-hacks right now, but could definitely be cleaned up. I've been aware of
this issue for a while, but didn't have a reason to fix until now.

This patch resolves both blurriness and DATA_ERRORs. 
Thanks!
