--- Comment #2 from Christopher Snowhill kode54@gmail.com --- I guess I can report it to the Wine developers, if you think this compiler error is occurring due to Wine translating the demo’s shaders incorrectly. I don’t know that it would be the demo’s fault, if it runs correctly on Windows, or runs correctly on NVidia proprietary drivers.
