wine users - Dec 2010 - Screen is unsynced with the window in Melty Blood: AC

I've got Melty Blood: Act Cadenza Ver B working somewhat through the latest
OSX version of Wine (I have Snow Leopard), the game itself functions well but
it's off center from the window, so there's some extra space left on the
bottom of the window and the top area is obscured, like so:

Can this be fixed easily, or is it a driver issue with my Nvidia card/some other
hardware?

A week without response? I should hope someone sees the thread this time D=
