--- Comment #91 from byteframe byteframe@gmail.com 2010-07-31 15:48:30 --- I've noticed a problem with left4dead under wine-1.3.0, I don't know if it's strictly related the srgb fix. The high-quality flashlight effect (present when you have "Effects Quality" set to >= Medium) will not work in multiplayer, unless you turn effects quality down to low, and then return it back to Medium/High -- while remaining in a game. If one were to start a single player campaign the high quality flash light effect will work immediately.
