I've confirmed it passes with llvmpipe

Is the only failing case.
Test now passes for me. Not sure if it was a Mesa or a CTS change.

FWIW, in order to pass, that test (and the one without _pbo) needs the library libtxc-dxtn installed on the system. That library is not officially available on several distros, needing specific ppas or similar. So it is really common to not have it installed on your system (at least it happened to me).
Ah, good to know. Thanks for the information.
