[MAME] "Mixed" rotated scanlines in vertical games

[mai]

Just wondering if there any chance avoid "mixing" (dunno know better word for it, 'cause I'm not really familiar with English take a look on screenshot) rotated scanlines in vertical games? All is going well with horizontal games: stretched well, scanlines looking good, no "mixing", - but stretching vertical games make it happens. It can be fixed changing "aspect ratio" or "clean stretch" options, but then horizontal games stretched in a wrong way.

 

PS: Yeah, I know it's working fine in newest MAME, but I'm using MAME 0.106 not official build - MAME32 Plus! Plus!

 

Here an example of so called "mixing":
