Ambient occlusion on Intel: enabled

Here is some screenshots of incorrect rendering in Planetary Annihilation. If
AO enabled I get really weird behavior when move or zoom camera: shadow is
moving all the time. It's working fine on R600g with same version of Mesa

Here is video on youtube:

I also will attach screenshots with correct (R600g, HD6950) and incorrect
(i965, HD4600) rendering. I tested it on vanilla Ubuntu 14.04 drivers as well
as Oibaf PPA.
