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. ** Bug watch added: freedesktop.org Bugzilla #79016 https://bugs.freedesktop.org/show_bug.cgi?id=79016 ** Tags removed: verification-failed ** Tags added: verification-done -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1318589 Title: [BDW] fix various GPU hang issues Status in “mesa” package in Ubuntu: Fix Released Status in “mesa” source package in Trusty: Fix Committed Bug description: Backport an upstream commit that fixes various GPU hang bugs on Broadwell. commit 9584959123b0453cf5313722357e3abb9f736aa7 Author: Kenneth Graunke <kenn...@whitecape.org> Date: Thu May 8 16:44:37 2014 -0700 i965: Fix GPU hangs on Broadwell in shaders with some control flow.
