The same problem does occur on LO 6.0.3 on Ubuntu 18.04. After looking through Arabic-specific issues reported upstream, I did find this: https://bugs.documentfoundation.org/show_bug.cgi?id=85426 . I think it's the same issue, although the bug title only mentions "fixing line space" and a specific font. I'm using a different font and I didn't fix any line spaces, just started typing in a new document. Do you think I should file this problem separately?
