GUI only draws alpha on older video cards?

    All GUI elements are rendering incorrectly on the 2 older video cards we have here.

    It seems to only render the alpha, not the color. There is one exception though: "GUI.DrawTexture" seems to work fine...

    Even simple text colors all render as black. If you choose the Dino graphics emulation, the text problem happens on the iMac too.

    Video Card that creates the problem:
    ATI Rage Fury Pro/Xpert 2000 Pro

    On the left is how it should look, on the right is what happens on this old card.

    Any ideas?

    This is ATI Rage specific problem (driver bug, and it won't be fixed in drivers because they are not updated anymore!). A workaround in Unity will be in upcoming Unity 2.1.
