843370 - Wrong accents in pdf, unless highlighted by mouse and focus lost

Status: VERIFIED FIXED

(Firefox :: PDF Viewer, defect)

Description

[Egmont Koblinger]

Attachment: The PDF that is rendered incorrectly.

Open the attached PDF file with the builtin pdfjs viewer.  (I'm using Firefox 19.0 on Ubuntu Quantal, as packaged by the distro).

The accented letters all look incorrectly, they are replaced by a symbol, as you can see on the attached screenshot.  Evince renders the document correctly.  (The document is in Hungarian, you should see familiar English letters, plus accents on some vowels, nothing fancier.)

If you highlight any part of the text, and then make the page area lose mouse focus (e.g. by clicking in the URL part, or focusing another window) then the accents become correct in the highlighed area.  You can also see that the spacing becomes a little bit different, i.e. on the screenshot the last letter of the highlighted text, an "o" does not completely hide the non-highlighed version of the same "o" letter.

Expected behavior: The letters should always be shown correctly. Furthermore, highlighing with mouse, or making the document lose mouse focus should in no way influence the look or the very exact position of the letters.

Some further examples:

http://www.bkv.hu/hajo/D11_.pdf -> Note the 45deg rotated text; after highlight and focus out, the version with correct accents is not rotated. I hope this might give you a clue where to look for the problem.

Verified the fix on latest Nightly and Aurora builds.
Will this be fixed on Firefox 20 beta, as well?
