I haven't tried on Windows.  But on Linux, all the Indic scripts are
displaying incorrectly, some showing on two lines instead of one, and
cursor movement through them makes the display change - probably an
indication that Emacs thinks it is displaying something different than
what is actually displayed at that point.

Yes, composition might be the common factor here, though I didn't see
any problem with Thai, which also uses composition but not
libotf/uniscribe.  I did not mean that it had anything to do with R2L,
just that the bidi merge was the point in time that this broke.
