Problem also in Libreoffice 7.1.2 in Fedora

Showing that it is not an Ubuntu specific error as problem persists in Fedora 34 with Libreoffice Community version 7.1.2
Comment 2 Julien Nabet 2022-02-26 09:23:35 UTC
6.4 LO version is EOL (End Of Life), like 7.0 and 7.1 branches.
Could you give a try to LO 7.2.5 or brand new 7.3.0 ?

On which Linux distrib are you? If Ubuntu, you can try repositories from LO ppa (see https://launchpad.net/~libreoffice/+archive/ubuntu/ppa)
Comment 3 Dr Anirban Mitra 2022-02-26 13:12:33 UTC
I installed Version: 7.3.0.3 / LibreOffice Community
Build ID: 30(Build:3)
CPU threads: 4; OS: Linux 5.4; UI render: default; VCL: gtk3
Locale: en-IN (en_GB.UTF-8); UI: en-US
Ubuntu package version: 1:7.3.0~rc3-0ubuntu0.20.04.1~lo1
from ubuntu ppa
However the problem persists - see screenshot

Thank you for your feedback.
Would it be possible you attach a minimal odt file (with an ad hoc Bengali character which triggers the pb) and provide some link to download the specific font you use?
BTW, does it happen only with a specific font or any font?

Test document to test the afrc feature

It occurs with my font and another font ShonarBangla.ttf by Monotype Corporation / Microsoft which is only other Bengali font I know to have this feature.

My font is available for testing at https://github.com/mitradranirban/fonts-mukti/releases/download/3.0.1/mukti.otf
Comment 6 Dr Anirban Mitra 2022-02-26 14:00:11 UTC

Comment 7 Julien Nabet 2022-02-26 20:34:43 UTC

It is not corrcted yet 
To see the proper expected rendering open the following webpage in firefox and compare the result with Libreoffice

Screen shot from firefox showing proper rendering

This is how the vertical fraction should look. Newer versions of Chrome also messes it so see the link https://fonts.atipra.in/afrc-test.html in Firefox only o see the proper rendering
