1300782 - Depending on gfx.font_rendering.fontconfig.fontlist.enabled, either Firefox does not use the GTK font for its interface, or some website text gets "out of line"

Status: UNCONFIRMED

(Core :: Graphics: Text, defect, P3)

Description

Attachment: jumbly.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:48.0) Gecko/20100101 Firefox/48.0
Build ID: 20160824215626

Steps to reproduce:

On Arch Linux, Plasma Desktop, Firefox 48.0.2

~/.config/gtk-3.0/settings.ini starts with:

```
[Settings]
gtk-font-name=Dosis Medium 16
```

Launch Firefox


Actual results:

Firefox will not use that specified font for the interface, unless I disable

gfx.font_rendering.fontconfig.fontlist.enabled

When that is disabled, the specified font is used for the interface, but some websites show text that isn't in a straight horizontal line: http://i.imgur.com/Yhtc00h.png (also attached)


Expected results:

Without disabling

gfx.font_rendering.fontconfig.fontlist.enabled

Firefox should have used the font specified in settings.ini for its interface.

I think there have been some relatively recent fixes that might be relevant to this. Do you see the same issues in a current Developer Edition (Firefox 50) or Nightly (FF 51) version?

Ah! As long as gfx.font_rendering.fontconfig.fontlist.enabled is set to false, nightly seems to make it all look good.

So unless it's wrong or a problem to change that value, and that code will make it to stable, this can be closed. Thanks!

Tested with FF 51.0a1.20160906.

Setting gfx.font_rendering.fontconfig.fontlist.enabled to false makes Firefox use an older implementation of its font-handling code. I expect this code will eventually be removed, so that "workaround" will not be available indefinitely.

So if you run Nightly with gfx.font_rendering.fontconfig.fontlist.enabled set to true (the default), what problem(s) do you see? I guess it still fails to use the Dosis Medium font from your Gtk configuration?

What kind of font is that? If you run

  fc-list | grep Dosis

in a terminal, what does it show?

Yes, when the setting is true the interface does not follow the GTK-set font.

Here's info on the font: https://fonts.google.com/specimen/Dosis

Here's that output:

/usr/share/fonts/TTF/Dosis-Regular.ttf: Dosis:style=Regular
/usr/share/fonts/TTF/TerminalDosis-Light.ttf: Terminal Dosis:style=Light
/usr/share/fonts/TTF/Dosis-ExtraLight.ttf: Dosis:style=ExtraLight
/usr/share/fonts/TTF/TerminalDosis-SemiBold.ttf: Terminal Dosis:style=SemiBold
/usr/share/fonts/TTF/Dosis-Light.ttf: Dosis:style=Light
/usr/share/fonts/TTF/TerminalDosis-Medium.ttf: Terminal Dosis:style=Medium
/usr/share/fonts/TTF/TerminalDosis-Regular.ttf: Terminal Dosis:style=Regular
/usr/share/fonts/TTF/Dosis-SemiBold.ttf: Dosis:style=SemiBold
/usr/share/fonts/TTF/Dosis-Bold.ttf: Dosis:style=Bold
/usr/share/fonts/TTF/Dosis-ExtraBold.ttf: Dosis:style=ExtraBold
/usr/share/fonts/TTF/TerminalDosis-ExtraBold.ttf: Terminal Dosis:style=ExtraBold
/usr/share/fonts/TTF/TerminalDosis-ExtraLight.ttf: Terminal Dosis:style=ExtraLight
/usr/share/fonts/TTF/Dosis-Medium.ttf: Dosis:style=Medium
/usr/share/fonts/TTF/TerminalDosis-Bold.ttf: Terminal Dosis:style=Bold

[Jonathan Kew [:jfkthame]]

So the font family name is apparently 'Dosis', and 'Dosis Medium' is the fullname of a specific face.

I'm not really sure offhand how all this interacts, but I wonder whether a settings.ini value of

  gtk-font-name=Dosis 16

would find the font? I'm not sure what effect that would have on other software, either, but it might be an interesting experiment, at least.

Also, does it show up in the list of available fonts in about:preferences#content?

Comment 6

[andydecleyre]

Removing "Medium" from the settings.ini does not make Firefox take the font assignment. Yes, "Dosis" can be chosen from the list in the preferences.

Comment 7

[andydecleyre]

Just popping in to say I still rely on this workaround with 51.0.1.

Comment 8

[andydecleyre]

Now that 55 is here, that config option seems to be gone/deprecated, and there's no controlling the UI fonts anymore. Maybe userChrome.css?
