Public bug reported:
I can't enable full hinting on fresh Kubuntu 24.04.1 install.
Previously I removed symlink 10-hinting-slight.conf in /etc/fonts/conf.d and
placed 10-hinting-full.conf symlink there and that was sufficient.
Now this action doesn't produce any result - font hinting remains slight. When
I open Font applet in KDE System Settings, the previews of Slight, Medium and
Full Hinting look absolutely the same.
What other things I tried:
Compiling older versions of libfreetype from 20.04 and 22.04 - former doesn't
work at all in 24.04, the latter shows no difference with the one shipped with
24.04.
Adding environment variable
FREETYPE_PROPERTIES="truetype:interpreter-version=35" - I noticed only slight
differences in diacritics, hinting remained the same.
Changing lcdfilter doesn't produce any result.
Changing mode="append" to more strict mode="assign" in hintstyle rule - no
result.
In the same time if I run 'xrdb -q', I see the next output:
Xft.antialias: 1
Xft.hinting: 1
Xft.hintstyle: hintfull
Xft.rgba: rgb
So it seems that hinting style is set properly after all, but it doesn't work
as intended.
The sole way I managed to activate it is to add 10-autohint.conf symlink, which
enables auto-hinter. But it isn't the desired result, as auto-hinter works
appropriately with very few fonts, the rest are rendered subpar when full
hinting is activated.
How can I enable full hinting with the native hinter, avoiding auto-hinter
usage?
Freetype library is provided by libfreetype6 (2.13.2+dfsg-1build3)
package.
