Hello,

I discovered that the font Arimo from the package fonts-croscore is rendered in weird way in Firefox.

Steps to reproduce:

- On Kubuntu Focal install package fonts-croscore
- Open a website that has text where Arimo gets chosen as font (Arimo seems to be considered as the default font for sans-serif text by Firefox when it is installed)
- The text looks a bit weird an ugly (at least to me)
- Compare the text in Firefox with the same text in LibreOffice Writer (choose Arimo as font)

In other applications as Firefox (e.g. LibreOffice, KDE Font Viewer, Chromium) Arimo looks exactly the same as the font Liberation Sans.

I managed to track this down - since the font is rendered correctly in Ubuntu with Gnome desktop, I looked for Kubuntu specific font settings and found out that the following passage in /etc/fonts/conf.avail/56-kubuntu-noto.conf is responsible for the bad rendering:

<match target="font">
    <!-- Turn on BCI (turn off autohint) for Arimo -->
    <test name="family"><string>Arimo</string></test>
    <edit name="hinting" mode="assign"><bool>true</bool></edit>
    <edit name="hintstyle" mode="assign"><const>hintfull</const></edit>
    <edit name="autohint" mode="assign"><bool>false</bool></edit>
 </match>

If I comment this out, then Firefox renders text in Arimo correctly like all other applications.

I have attached two screenshots that compare the rendering in Firefox with default settings and with the respective passage in /etc/fonts/conf.avail/56-kubuntu-noto.conf commented out.

Kind regards,
Jan
