Doesn't look like a proper dupe. In  bug 113428 characters fully overlap, or
worse; with this bug, it's more of a spacing issue.

Also, 113428 does not manifest with 5.4.

Of course... it's not impossible that fixing that one somehow affected this one
but I really can't say. And they're both about horizontal placement of glyphs
on a line, so they're obviously related.

Khalid fixed that bug on the 8th and if this bug is still showing up with
Omer's build from the 13th then it wouldnt be a duplicate.

This bug needs to be bibisected to know where the issue first arose.

All Culmus fonts, you mean? Or have you seen this with other Hebrew fonts?

Confirmed both Linux (latest 5.4 RC) and Windows (5.4.1.2). Problem occurs with
all fonts, including David and Narkisim. I guess it has something to do with
the internal representation of the text.

close comparison 5.3 vs 5.4

Looking at the PDF comparison, it looks like certain groups of letters are
shifted right, leaving their surrounding intact - see attached "5.3 vs 5.4
close comparison" image (made from jay's PNG)

The shifted groups (first line only) are
 * ayn-resh
 * lamed-yod
 * nun-vav-gimel-ayn
 * lamed-alef-vav-pe
 * he-lamed-vav
 * samech-pe-yod
 * het-shin-bet-vav-nun-vav
 * bet-alef
 * alef-het

Honestly, I can't see any logic in this collection.

--- Comment #9 from Eyal Rozenberg  ---
Also note that some letters are spaced slightly too far apart. I wonder if
there isn't some kind of "index-is-off" issue here in accessing the amount of
horizontal space necessary per character.

--- Comment #7 from Yousuf Philips (jay)  ---
The overlapping characters is clearly a regression introduce in the 5.4 cycle.
The close Heh and Ain characters varied in 5.3 and 5.4 based on whether it is
in a numbered list or not, 5.3 but in my tests never was as close as in
attachment 136815. Tested on Linux Mint 18.0.
