Subject: g33: tiled output

Hi,

For some time, I'm seeing a tiled output like:
http://www.fi.muni.cz/~xslaby/sklad/panics/bad_tile.png

This happens sometimes when I open selected pages in firefox. Like
maps above.

Currently I'm running 3.2.0-rc3-next-20111130. This started appearing
after I switched to desktop fx. Will anything from the debugfs help to
track this down? Or better to report this to freedesktop.org?
