Hello Timo, or anyone else affected,

Accepted mesa into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/mesa/10.1.3-0ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

piglit tests: no regressions on snb, 13 more tests now pass

Seemingly a regression on nv96 with spec/ARB_timer_query/timestamp-get, but after examination it is probably a result of running all tests in parallel. Quite a lot MSAA tests started to pass. 14349 -> 14415

On ATI spec/EXT_transform_feedback/tessellation quad_strip flat_first seems to start failing, a real regression. I'll attempt to bisect it.

I'm tagging it verification-failed based off of Maarten's last comment regarding a regression.

For reference:

https://github.com/blazt/piglit/blob/master/tests/spec/ext_transform_feedback/tessellation.c

I've filed a bug upstream, and it was closed with NOTABUG:
"the order of tessellation within a primitive is undefined"

https://bugs.freedesktop.org/show_bug.cgi?id=79016

To be fair, the test doesn't fail, but it produces a WARN, which is allowed.

As a result, marking test as verification-done, rather than verification-failed.
