Hi, while trying to debug the problem described in https://bugs.documentfoundation.org/show_bug.cgi?id=157348 further I'd like to understand how font rendering w.r.t. hinting is done in libreoffice for Linux. In 7.4.7, Microsoft fonts like Arial are shown with thin lines when FREETYPE_PROPERTIES="truetype:interpreter-version=35" is set and <match target="font"> <edit name="autohint" mode="assign"> <bool>false</bool> <edit> <match> is defined for Arial (or in general) in e.g. ~/.config/fontconfig/fonts.conf. When setting the interpreter-version to 40 or autohint to "true", Arial and all other Microsoft fonts are way thicker. In LO 7.5.* and later, all Microsoft fonts are always thick. So either "truetype:interpreter-version=35" is no longer respected by libreoffice, or autohinting is always forced regardless of the fontconfig settings. But from looking at the libreoffice source code, it seems that it just relies on the settings it finds in fontconfig. Can someone tell me if the decision about autohinting etc. is done inside libreoffice at some place? Or does it fully rely on the external settings of fontconfig? Is it possible that libreoffice > 7.4.7. enforces autohinting internally? And/or could would the missing support for "truetype:interpreter-version=35" come from inside libreoffice or from an external library that libreoffice is linked against? Thanks a lot! cu, Frank
