Comment 1 bo.b.wang 2011-10-24 19:54:04 UTC
By the way, this demo will render wrongly on IvyBridge, SandyBridge, PikeTon.
Comment 2 Tapani Pälli 2012-05-14 01:15:49 UTC
I've just tested this on Sandybridge with mesa 7.11.2, works and renders fine, no errors.
Comment 3 Chad Versace 2013-05-31 22:50:09 UTC
Path submitted to list that fixes the bug on Ivybridge and Haswell.
Subject: i965: Fix glColorPointer(GL_FIXED)
Comment 4 Chad Versace 2013-06-03 20:25:00 UTC
I've confirmed that this commit fixes the bug on Ivybridge and Haswell. Sandybridge and Piketon are untested. (What is Piketon?)

Could QA please validate on Sandybridge and Piketon?

Xun, please verify.

Piketon is the Ironlake desktop platform name.

Waiting on QA to close the bug. I verified the fix on Ivybridge and Haswell.
