With mesa at commit 6d1cecb (Friday evening) this problem is fixed.
Thanks!
P.D: Maybe it was related to the hyperz problem of r600g drivers, as I am using a revision that is after this commit http://cgit.freedesktop.org/mesa/mesa/commit/ ?id=01e637114914453451becc0dc8afe60faff48d84
Could you set the following environment variable to re-enable hyperz?
R600_DEBUG=hyperz
