Description Zayed Al-Saidi 2022-07-06 19:03:16 UTC

Created attachment 150450 [details]
test document

The Arabic inline notes are not rendered correctly. It lacks the bidirectional text support as well as the proper shaping (i.e. the letters are disconnected.)

In the attached test document, the same text which are in original PDF is put as inline note. 
The text is: بسم الله الرحمن الرحيم

Do I understand that you're saying that both lines of text should be rendered the same?

Not even Adobe Reader is doing that https://i.imgur.com/59UpQfa.png  

Which if I'm not making a mistake is exactly the same that Okular renders, no?

Yes. They should be rendered the same.

It is a bug in Adobe Reader :) and I can't report it because it is a closed software.

Unfortunately, you are correct.
