This was just fixed in svn.
A few artifacts remain when multiple bitmaps (> 2) overlap, but this will hopefully improve some day when libass gets RGBA rendering. It doesn't seem to be possible to get around it with the current rendering model.

That new SVN really fixes that worse part of that, but as you said some "lines" over that border still remaining,
r28893

and problem doing really only alpha on border...

btw why in older revision that problem has not been?
