House of the Dead: Overkill - strange 'ghosting' problem

[LordBarker]

Hi all,
have tried a few revisions of Dolphin now and keep experiencing the same issue. On Overkill the game runs at perfect speed and all menus etc. are perfect. However when I start the main story mode, the cinematic sort of doubles-up over itself and creates a weird ghosting effect which then continues through the game, making it incredibly distracting. I have tried numerous config and graphic settings and cannot get rid of it. I have tried both the Mac builds (since I'm on an i7 iMac running Bootcamp) and Windows builds and no luck. Any ideas?
Cheers
