--- Comment #2 from José Suárez j.suarez.agapito@gmail.com --- The last good known version is d571f2, and the first known bad version is 9f2050.
I will try to narrow that a bit but, aAs stated, it is a bit difficult for me to bisect. I am using oibaf's ppa which I can recompile myself in a chroot environment. However, since I am not used to working with git I presume it will be a bit tricky for me to obtain the diffs to be applied.
I know this is noob, but is there a way to obtain a diff between version from http://cgit.freedesktop.org/mesa/mesa without having to clone the git repo? That would surely help me identify the offending commit...
