I can confirm the bug on my hard/soft configuration:
card: i915 gm os: Ubuntu 9.04 * kernel: linux 2.6.30 rc6 vanilla xorg driver version: 2.7.1 stable libdrm-intel: 2.4.9 mesa: 7.4.1
* I have installed on Ubuntu Jaunty packages from xorg-update PPA repos and mesa from karmic repos: this not solves the issue.
