Not really an issue. It's a related to 4:3 default scaling method which adds or 
remove lines to achive the desired aspect. The default method is faster. It use 
the lower resolution posible for speedup  so artifacts are more visible.
Anyway yo can select a fixed emulation resolution to minimize artifacts in 
mame4droid menu.. for example 512x384... if the resolution choused is too 
higher you can have performance issues, overlaping frames... so chouse with 
care...
other way to completaly removce artifacts it is pressing coin+star to acces 
mame internal menu and in video options select pixel aspect ratio option.. this 
is how drawed mame4droid 1.0

Setting video mode to pixel aspect ratio solves the problem. Thank you
