--- Comment #5 from thanoulas thanoulas@gmail.com 2013-07-31 12:52:05 CDT --- I highly doubt that apple would ever fix this, as (per your description) wined3d provides two buffers to opengl when it should only provide one. So I guess this should be fixed in wined3d, or at least have a registry value where someone could disable the effects of this commit?
