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

Comment 10 Eric Anholt 2010-01-30 15:28:12 UTC 
This fixed other issues in QT GL backend rendering like this (qtdemo), so I'm assuming it fixed this one.
