Status: NEW

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.0.249.0 Safari/532.5
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.5) Gecko/20091130 Shredder/3.0

I used gnome to specify font rendering settings: subpixel smoothing, slight hinting, 96 dpi (xdpyinfo also reports I'm using 96dpi).  I compiled thunderbird with these options:

ac_add_options --enable-default-toolkit=cairo-gtk2
ac_add_options --enable-system-cairo
ac_add_options --enable-freetype2

Thunderbird's application fonts don't seem to use my system font hinting settings.  They're over-bold, which seems to be caused by using "full" hinting or the like.  Have I failed to compile in proper support for font rendering, or otherwise missed something?

Reproducible: Always

Do you have the same issue if you use Firefox 3.5 ?

Yes, I just compiled Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.5) Gecko/20091201 Shiretoko/3.5.5 with the same font and toolkit options and with system cairo and has the same issue.

Reproduced with Firefox 3.5.5, Firefox 3.6 beta 5, Firefox 3.7a1pre.

No matter uses system cairo or mozilla tree cairo.

gnome-font-appearance sets Xrm settings, XSETTINGS, gtk-xft settings, and gconf.

cario-xlib-screen.c uses XGetDefault(), which can get the setting of gnome-font-appearance.
Surface font options were set on the pattern in cairo_ft_font_options_substitute.

gfxPangoFonts.cpp gets options by FcPatternGetInteger() FC_HINT_STYLE, FC_RGBA, etc.
Then it does cairo_font_options_set_hint_style(), cairo_font_options_set_subpixel_order(), etc.

I think the expected result should be cairo font options for screen should have the priority.
It seems it doesn't work as expected.

I don't know what that means.
