In order to solve other issues, I am now running the latest intel drivers, together with kernel 3.4.4 on a DELL E6500 with intel graphics and Kubuntu linux 12.04 64 bit. Since these drivers support sna acceleration, I have decided to give it a try. Most things appear to be working. However, major issues exist with the libreoffice application. Specifically, running Libreoffice Impress some graphical elements are not shown on screen at all. Hardware: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller Software: Kernel 3.4.4 (from ubuntu mainline PPA) libdrm 2.4.37 + git 120716 mesa 8.1 + git 120608 xserver-video-intel 2.19 + git 120713 (this later stuff from the oibaf graphics drivers PPA, aka Fabio Pedretti's PPA) To reproduce: 1) put accelmethod sna in xorg.conf 2) Run libreoffice impress Actual result: 1) See that in many slides, the background appears gray instead of white as it should. 2) See that many mathematical formulas (OLE objects in libreoffice) are not displayed. Reverting to uxa acceleration on the same driver fixes the visual issues.
Please attach a good/bad screenshot so that I can be sure I'm hunting the same issue.

commit 907a2a7c97514d3f7610648ed87c7042a857f786 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Jul 16 14:47:03 2012 +0100 sna/trapezoids: Fix inplace unaligned fills (on gen4) Reported-by: Sergio Callegari <sergio.callegari@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=52150 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Haven't checked the OLE objects just yet, though very likely to be the same bug.
As soon as the current git, with the above commit, gets into an updated deb on the ubuntu ppa, I'll provide some feedback about the libreoffice OLE. Thanks for the very quick response!
I confirm that it seems to be ok with the latest packaged git driver (20/7/12)
