]]>* freetype2 with freetype2-infinality,
* fontconfig with fontconfig-infinality,
* libxft with libxft-cleartype,
* cairo with cairo-ubuntu.
They should significantly improve the rendering of your fonts. Of course, you can always check other versions of the packages in the AUR: I assume that the above combination should be safe in most cases, and the final result satisfactory for the user.
Edit 1: It's worth reading the Wiki article on font configuration to get the idea what and how can be tweaked.
Edit 2: And here comes a screenshot:
]]>$ cat /etc/fonts/conf.avail/75-fix-calibri.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!-- Use embedded bitmaps in fonts like Calibri? -->
<match target="font" >
<edit name="embeddedbitmap" mode="assign">
<bool>false</bool>
</edit>
</match>
</fontconfig>
$ ls -l /etc/fonts/conf.d/75-fix-calibri.conf
lrwxrwxrwx 1 root root 33 Mar 1 12:43 /etc/fonts/conf.d/75-fix-calibri.conf -> ../conf.avail/75-fix-calibri.conf
And after restarting X it looks a lot better, but the ligatures still look a little bit different, kind of slightly bold. Any other ideas?
And I don't know what you mean by 'freetype2 branch' but here's a basic pacman query if it helps:
$ pacman -Qs freetype2
local/freetype2 2.4.8-1
TrueType font rendering library
Thanks again!
]]>Edit: Despite freetype2, you may try putting
<!-- Use embedded bitmaps in fonts like Calibri? -->
<match target="font" >
<edit name="embeddedbitmap" mode="assign">
<bool>false</bool>
</edit>
</match>
somewhere in your fontconfig files (or first check where it sits in your /etc/fonts/conf.d and disable it).

For example, I just noticed that Twitter, transparently to me and presumably all other Twitter users [...]
[...] such as swiping left or right with four fingers to switch between apps.
In bold are the charecters that stand out (and I mean it) when reding the text. I dare not post a screenshot, for I believe this may kill your soul as it has been slowly killing mine.
So far, Calibri is the only font that I found that shows this behaviour, and it's not in all programs. Some affected programs are Firefox and Thunderbird. In LibreOffice, for example, it shows normaly.
I do not remember having done any font configuration in my system, but I'm not sure where I should check...
Thanks for your help!
