So you are saying that this character was not displayed correctly,
i.e. DAGESH was not inside LAMED?  If not, what is the problem with
displaying this character and the characters around it?

Anyway, it is very strange that only you see these problems.  Would it
be possible for you to build the latest master branch of the Emacs
development repository?  There we support text shaping with HarfBuzz
(which you will need to install separately before building Emacs), so
any potential problems with libm17n-flt you have installed should not
affect the display.
