--- Comment #1 from Marek Olšák <maraeo at gmail.com> ---
This is a known issue and I mentioned it on the mailing list. There seems to be
a bug in softpipe's culling or clipping.

The problem is if one of the vertex coordinates is negative, the whole
primitive is culled. llvmpipe takes the same codepath in gallium components as
softpipe (except for Draw?) and doesn't have the issue.

To see the problem clearly, run fbo-blit-stretched with the first argument
being the test index.
