Summary 05309: Many systems that use multiple screens: Only one screen shown when using multi-screen games with an overlay effect enabled in Game Properties.
Description If you use an effect overlay (scanlines or apertures etc.) only the left screen is displayed in dual or triple screen side by side mode. This appears to have changed since 0.149 as this functionality worked fine in that.

Disabling effects allows the games to show multiple screens.

Have tested with Darius, Darius II, Ninja Warriors, Backfire! and it affects all of them in the same way. Also affects vertically arranged screens e.g. spnchout - in this case only the top screen appears.
Steps To Reproduce In MAMEUI, go to the 'Advanced' tab in Default Game Properties and add an effect (e.g. Scanlines75x2_J4) to otherwise default settings. Then run one of the above games, and the problem should be obvious.
Additional Information Tested with 32 & 64 bit versions of MAMEUI 0.150, which both exhibit the same behaviour.

 I've noticed it also affects vertically arranged screens as well, e.g. Super Punch-Out. I wonder whether it's related to http://mametesters.org/view.php?id=5321 also?
