It looks like the diacritics are not placed properly when they occur
on the initial lam-meem ligature (and perhaps this applies to other
ligatures as well).
This is not a fontspec problem. It may be a bug in the OpenType layout
library that xetex is using, but to investigate it I will need to have
an example of a font where this happens. I don't have the Yakout font
you're using; can you test whether you see similar problems with any
freely-available Arabic fonts?
(Why is there "xx" on the end of the font file name in your example --
is this a font that has been modified in some way?)
