User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

Linux Firefox 1.5b1 render a different font on this site than when Firefox 1.0.6
is used. The 1.0.6 font is better looking and i think that was the page designer
intention. A comparison screenshot will be added to the bug.

Reproducible: Always

Attachment: Comparing font rendering with 1.0.6 and 1.5b1

This was taken using the original Firefox releases from Mozilla.org, in order
to no compare custom Firefox from the Linux distribution with Firefox 1.5b1.
Running on Fedora Core 4

Go to http://members.ij.net/mrmazda/auth/dpi-screen-window.html and see if both report the same DPI.

Attachment: DPI comparation

Both report 96 DPI.. but the selected font is different. The first table is firefox 1.5, the other one firefox 1.0.7

I saw this on a Red Hat system the other day after upgrading from 1.0.7 to 1.5.

Comment 6

[Felix Miata]

Looks to me like your 1.5 profile's default sans-serif font is Nimbus Sans L, and your 1.0.6 profile's default sans-serif font is Bitstream Vera Sans. Vera is considerably larger for any given nominal size than Nimbus. Vera @ 16px is about the same size as Nimbus @ 18px.

Both version was tested using a nre profile, so it is using default font mappings. I found another font rendering problem:

When no lang attribute is used Japanese characters are shown with a different font, one that is not scalable. when using the attribute, the rigth font is used. That never happened on Firefox 1.0.x. See the attached files

Changing version to 1.8 branch because it exists on released Firefox 1.5

Does this bug occur in a recent trunk build?

Both test cases render identically for me with FF8.  Closing.
