Hi,

I am building the master branch.

I am using :
Ubuntu
Version 12.04 (precise) 32 bits
Kernel Linux 3.2.0-60-generic-pae
GNOME 3.4.2

The output of clinfo is in the attached file.

    Btw, which branch of LibreOffice are you building? master,
    libreoffice-4-2, ...?

    It would be nice to trim log files to the necessary parts.. which is

    So strangely your combination of OpenCL driver and graphics card
    produces quite a large difference in the result.

Please share the output of clinfo and your exact system (e.g. OpenSuse AMD drivers for example are known to be problematic).
