--- Comment #6 from Stefan Dösinger stefandoesinger@gmx.at --- I'll have a look at this function and see which check we fail, but I have my doubts that it is Wine's fault. This code works fine on all other drivers - nvidia, fglrx, r600g, osx drivers.
Also keep in mind that MSAA in Wine apps fails if Wine doesn't request the multisampling, but it is enabled with GALLIUM_MSAA=n. I don't see how this can possibly be a fault in Wine.
