I did find my old patch but it fixed nothing.  I'd really like to fix this, but
there seems to be something very broken with depth in llvmpipe, that goes
beyond the precision lost due to unorm24 <-> float32 conversions.



I've also looked at the trace more closely:

One thing odd about it is that it starts using the stencil buffer without
clearing on the first time (it only clears the color and depth buffer). But I'm
not sure if that's the problem.

Also the issue can be seen as early as draw call 837.

The first stencil clear is ironically, at call 838.
