Is this a regression?
(In reply to comment #7) > Is this a regression? No, Jonathan didn't run this test on any earlier version, so probably not. He tried with UMS instead of KMS, though, and that didn't change anything.
Even though I forwarded this bug from Jonathan Wheare, I can also reproduce it on my Thinkpad X61 Tablet with 965GM. I have checked that it is also present with the latest ubuntu xorg-edgers repository, https://launchpad.net/~xorg-edgers/+archive/ppa . This currently has * mesa 7.7.0~git20091008.f49d5359-0ubuntu0tormod * libdrm 2.4.14+git20091007.3a7dfcdf-0ubuntu0tormod2 * intel driver 2:2.9.0~git20091007.03e8e64f-0ubuntu0tormod3 * xorg-server 2:1.6.4.901+git20091005+server-1.6-branch.c07b2368-0ubuntu0sarvatt
This fixed other issues in QT GL backend rendering like this (qtdemo), so I'm assuming it fixed this one. commit 22bbc979944084ddffbb2c42a8178e172beaece0 Author: Eric Anholt <eric@anholt.net> Date: Sat Jan 30 15:11:09 2010 -0800 intel: Respect texture tiling when doing a PBO blit teximage upload. Bug #26008. Fixes piglit pbo-teximage-tiling-2.
