Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a3pre) Gecko/20070308 Minefield/3.0a3pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a3pre) Gecko/20070308 Minefield/3.0a3pre ID:2007030804 [cairo]

I'm seeing this on Windows so far only with the DejaVu Fonts. Some charakters are completely invisible and sometimes whole lines are overlaid on the place of one single character. There are also some selection problems.
I'm seeing this no longer than a week so it could be a regression from bug 370588. I haven't tried it on an other platform and i couldn't reproduce the bug with other fonts. And it's not a problem of the font. It works on other Browsers and it worked with Minefield too a week before.

Reproducible: Always

Steps to Reproduce:
1. Install the DejaVu Fonts on Windows
2. Open http://dejavu.sourceforge.net/wiki/index.php/Testing
3. Observe
Actual Results:  
Characters are invisible or overlaid

Expected Results:  
Text should be drawn correctly

Can you also reproduce the problem with the latest nightly?

I allready use the lastest nightly: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a3pre) Gecko/20070308 Minefield/3.0a3pre ID:2007030804 [cairo]
I also get a crash when I try to select some text:

I think that this is a dup of bug 372838. The current Uniscribe code was broken by bug 370588.

[Stuart Parmenter]

This seems much less broken than the original screenshot.  I see problems in both DejaVu Sans Mono examples but they're fairly minor in the first (i.e. only the last few characters seem to get screwed up).  The arabic stuff looks almost right but the spacing is way off and the boldness is wrong.  Some of the characters are missing glyphs so we're doing font fallback.  This should get a little better after I fix 332649.
