With HW acceleration disabled, characters are not displayed at all.

Scoobidiver, are we talking about http://www.dicosmo.org/HoldUp/HoldUpPlanetaire.pdf ?

[Yury Delendik (:yury)]

Sorry, I did not notice it suppose to be tested *without* the hardware acceleration. Reducing the scope of the bug.

Even with HW acceleration turn on, issues are there (see the first screenshot).

That bug is about not displaying characters or displaying them with a wrong size at a certain zoom level. This bug is about displaying characters with wrong font.

Comment 20

[Vincent Lefevre]

Similar problem with Iceweasel 19 under Debian: special characters (such as the fi ligature as generated by LaTeX and some characters in math formulas) are replaced by random characters. And "normal" text rendering is ugly, probably because the font used is different from the one embedded in the PDF file.

Comment 21

[Scoobidiver (away)]

After MS KB2670838, I can't reproduce those issues.
Here is the DirectWrite version:
DirectWrite activé: true (6.2.9200.16492)

WFM on a german Windows 7 with KB2670838 applied against Firefox 19 and Trunk.

Not for me with Firefox 19 on Ubuntu, nor on Mac OS X.

Different testcase and also OS = different bug.

Comment 28

[Vincent Lefevre]

Users on other platforms should look at bug 738627. This is precisely the problem I'm seeing.
