Description

10 years ago
User-Agent:       Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9b3pre) Gecko/2008011404 Minefield/3.0b3pre
Build Identifier: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9b3pre) Gecko/2008011404 Minefield/3.0b3pre

The nighlty builds have a significantly degraded font rendering quality.
Fonts don't display in there requested color, e. g. black, but in a mixture of red, black and green for instance, which is quite likely a hinting problem.
FreeType's autohinter is used. 

(When using bytecode-hinting, the fonts look like in Firefox 2: http://ochsenreither.de/~soc/rendering_h-strong.png )

Reproducible: Always

Steps to Reproduce:
1. Start Firefox
2. Browse to any website
Actual Results:  
Fonts will look ugly.

Expected Results:  
Fonts shouldn't look ugly, at least the level of font quality seen in Firefox 2 should be reached.

In my opinion the severity is 'major', because readable text is one of the most important features a browser should provide.

(Additionally, I don't want to stay at Firefox 2, because of that unbearable bug ... so hopefully it gets fixed faster that way :-P)

here is a close up that shows the difference between rendering.png and rendering_ok.png

Here is a close up that shows the difference between rendering.png and rendering_ok.png (I agree it looks worse in ff3 but when these images were zoomed out I didn't see the difference directly).

same page rendered in ff2 and ff3-nightly-minefield-2008011604

Exact version of ff3 nightly build was:

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b3pre) Gecko/2008011604 Minefield/3.0b3pre

Looks almost identical on my machine, maybe it uses some other kind of hinting or something?

Fonts appear fine to me on nightly:

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b3pre) Gecko/2008011704 Minefield/3.0b3pre

Kubuntu 7.10

Martin, what distribution are you using?

This is certainly bug 404637

Some distribution patch Cairo so that you get less color fringes when not using the autohinter.

err, rather when using the autohinter (or not using the bytecode interpreter)
