--- Comment #8 from Ruslan Kabatsayev <b7.10110111 at gmail.com> ---
Hmm, I seem to have expressed my question badly in comment 7. I mean: 

1. with s2tc library and no s3tc, i965 result is correct, and swrast result is
wrong
2. without s2tc but with s3tc library both are correct (as expected)
3. with both s2tc and s3tc removed both swrast and i965 are broken completely

So the question is now: why is i965 broken without s2tc if it seemed to decode
the texture without shortcomings of s2tc when s2tc was installed? How is swrast
different from it in this regard?
