--- Comment #1 from Kenneth Graunke kenneth@whitecape.org 2012-06-12 08:09:02 PDT --- Hmm. That patch shouldn't have changed the result at all---and it does look fairly close---so I think your hardware just has somewhat lower precision than mine. The Piglit test uses GL_RED_SIZE etc. to determine the tolerances/precision expected, so with the increase from 4 to 8, the test became more stringent.
Normally this would make sense, but since GL_RED_SIZE and friends are /approximate/ precision for a compressed format---and in this case, the /maximum/ precision---I think we may need to lower the test's tolerances.
Changing this to a Piglit bug.
