130366 - Times font displays poorly; selecting text causes it to move (keywords selection adobe highlight)

Status: VERIFIED INVALID

(Core :: Internationalization, defect)

Description

[C. Scott Ananian]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020310
BuildID:    2002031008

With the mozilla font preference set to 'adobe-times-iso8859-1' for the Serif
font in the Western encoding, font layout is broken: on
http://www.mozilla.org/start, for example, there is a large space at every place
where the font style changes (before the first 'known about' hyperlink, for
example, and after the 'please turn it on' italic text).
Furthermore, selecting any text on this page causes the selected text to jump
(to what it looks like is it's "proper" place, based on where the weird
whitespaces fall).

Setting the font to microsoft-verdana-iso8859-1, or adobe-helvetica-iso8859-1
works fine, but setting it to adobe-palantino-iso8859-1 breaks in the same way
times does.

Reproducible: Always
Steps to Reproduce:
1.Start mozilla.  Load http://www.mozilla.org/start/
2.Set the your serif font preferences for the Western encoding to
adobe-times-iso8859-1 or adobe-palantino-iso8859-1, and tell mozilla to use the
Serif font for proportional text.
3.Highlight "check that it's not already known about".

Actual Results:  After step 2, odd spaces at font style changes. (see
description above).
After step 3, the unselected text jumps to the right as you extend the selection.

Expected Results:  No weird spaces.  Selecting text shouldn't move it in any way.

I will attach screenshots.  This in the talkback x86 build from www.mozilla.org
running on a recently-updated 'debian unstable' box (the debian 'unstable'
distribution is slated to become the new debian 'stable' distribution real soon
now).  This did not occur on mozilla 0.9.8.  The "new" mozilla truetype support
is *not* enabled (although my x font server is configured to serve truetype fonts).

Bug 75011 looks similar, but it's probably not related (as this bug occurs for
non-bidi text).

Attachment: Screen shot of http://www.mozilla.org/start showing bad font layout.

This is a screen shot of http://www.mozilla.org/start/ in adobe-times-iso8859-1
showing the bad layout.  See particularly the large spaces around the
hyperlinks in the main text.

Attachment: Screen shot of http://www.mozilla.org/start using Palatino font.

Screen shot of the same page, but in adobe-palantino-iso8859-1 font.  The page
looks even worse!  Note that mozilla 0.9.8 didn't show this behavior (ie it's
very unlikely to be a font configuration problem on my machine).

Changing to INVALID.  Seems to be an interaction with the gdkxft package (even
though mozilla is marked as a program *not* to use gdkxft on) -- unsetting
LD_PRELOAD so that /usr/lib/libgdkxft.so isn't included fixes the problem.

I've moved this to sourceforge bug 529158 on gdkxft
http://sourceforge.net/tracker/index.php?func=detail&aid=529158&group_id=38513&atid=422541
and debian bugs 138076 and 138077 on libgdkxft0 and mozilla-browser:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=138076
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=138077

If other people see this bug, you can follow up there.

For what it's worth, there is a patch to mozilla to fix this available from
