Example

Hi. Please open attached file. This created my me using LibreOffice. It contain same statement repeated in 4 Arabic fonts numbered from 1 to 4. Each font included same statement in 2 sizes except 4th which in 3 sizes.
 Issue is old since version 3 when I 1st met LibreOffice & was very sever & led me to not use program. Since version 4.3.0 it became less so I started to use software really. However issue still exists but less sever.
 With Arabic characters, at certain font size - deffer according to type of font - there will appear a tag or dot at end of certain characters.
 In the attached file it appear with terminal character ج in small size line for each font except 4 font where it appear in largest font size in the character و (on character right side). If you take line of issue & change it's size to sizes that do not show issue then the tag will disappear. If you return to previous size then it will reappear.
 Best

There are indeed pieces of kashidas appearing when font size is about 12 to 14 pt.

https://blog.documentfoundation.org/blog/2016/04/28/coming-up-the-month-of-libreoffice/

Please consider fixing this old & long standing bug during your work in May. 

This bug is one of most bad bugs regarding support of Arabic language.

I can’t reproduce this, but I’d say it is a new bug either way.

Tested LO 3.3 and 4.4 and the same thing happens of it appearing and disappearing at different zoom levels.
