https://bugs.winehq.org/show_bug.cgi?id=36789 --- Comment #3 from Henri Verbeet <hverbeet(a)gmail.com> --- Apparently the driver just doesn't expose the functionality, there's not much we can do about that, unless there's a different extension exposing the same functionality that the driver does support. There's one other possibility, and that's that the functionality is only exposed in core profiles, either through GL 3.3, or some earlier version + ARB_blend_func_extended. In that case this is blocked on wined3d supporting GL core profiles, which will happen eventually, but may take a while. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
