@Rachel: Could you please retest with the mesa patches of christian I sent you some = time ago ( http://cgit.freedesktop.org/~deathsimple/mesa/log/?h=3Dxbmc-test ) and important: together with this ppa: = https://launchpad.net/~wsnipex/+archive/xbmc-nightly/+packages That does unmapping / mapping of surfaces everytime and the AMD folks consi= ders our "usage of mapped surfaces" as wrong spec - which they are pro= bably right, despite it is working perfect since more than 2 years. That mesa 10 is working for us is "pure luck" I was told on IRC. = Cause I am not such a lucky man, we need to investigate further ;-)
