    Hi guys,

    The vignetting shader does not give desired results on iPad2 when MSAA is enabled. Instead of darkening the corners, they are brightened.

    This is a bug you should fix your end for 3.5, probably an easy fix, oversight sort of thing. I mention it because the vignetting documentation lists mobiles as being compatible, therefore it is a bug.

    It works fine without MSAA on iPad2.

    Being mobile compatible does not mean it works with MSAA that messes around on the rendered buffer after the frame has finished its rendering actually (same as not all desktop compatible shaders will work with AA or AA not working with some post fx anymore)

    Also if it is a bug, you know the procedure of reporting it, not here ;)

    It's a pain for something so simple as text to go through the unity menu. I think it has something to do with the changes unity made since 3.3.

    Not sure how to fix it though. Thanks for the buggy driver, apple.

    well, try to check shader source if it has RGB color mask (and change for rgba)
