Hallo,

in the INSTALL instruction of Emacs we read:
(On GNU and Unix systems, Emacs needs the optional libraries "m17n-db",
"libm17n-flt", "libotf" to correctly display such complex scripts as
Indic and Khmer, and also for scripts that require Arabic shaping
support (Arabic and Farsi).)

But I noticed that libm17n-flt isn't installed and it's not a package in the repository of Archlinux . I didn't need to install it before.

Can it be the problem? Or is it included in the other packages (m17n-db, libotf)?

Should I install it from here:
https://pkgs.org/download/libm17n-flt.so.0()(64bit)

?

Regards

Thanks for the answer. Good news  that one problem is solved.

I didn't mention details because I assumed that's the same problem and it wasn't my main question there. I
chose the reproducable proble. 

But now some details:
- I don't use ivy or ido
- The problem happens after "some time" of working with Emacs, usually not directly after starting Emacs.   
  Example : the 3 attached pictures are of the same text file (not org or outline), but with different text sizes. I
have just the Arabic word العربية in it. And I'm using a monospaced Font: Dejavu Sans Mono.
  In 'text8correct.png' everything is fine, "text size": +8 word , if I decrease to +7, the shape is not correct the
glyphs are too dense. It remains incorrect until the size +5. At +4 it becomes correct again.
  But if I open the same file with a new Emacs process I don't have any problem!

I can only hope this is due to the same problem as was fixed in
bug#44521.  If not, let's hope someone will come up with a
reproducible recipe in the future.


Also what happens:
- Sometimes the letters don't have the correct form: a middle form for an ending letter 
- Sometimes the letters are disconnected as in bug#44521.

I attach below the images you sent, so that they are stored with the
discussion:
