      After upgrading 5.13.2->5.14.0 font rendering is changed in KDE applications despite no config changes were made. I have full hinting in fontconfig (see the attached config file), but after upgrade fonts are rendering with slight/no hinting (so, system configuration is ignored). In GTK applications everything is fine and fonts are rendering as before (full hinting). Downgrade to v.5.13.2 helps.

       

      UPD: setting `QT_AUTO_SCREEN_SCALE_FACTOR` to `0` or `QT_ENABLE_HIGHDPI_SCALING` to `0` helps me to get the proper font hinting on 5.14.0. But my DPI is not high (96).
