@mgiammarco: I'm not a font expert, so this discussion is a bit over my head, I think. Nevertheless I miss some basic information which I believe is necessary to understand the nature of your observation:
* Which are your effective fontconfig settings? * Which font(s) are not rendered as you would expect? As regards the default RGB settings, they were changed in 23.04 in all other flavors but Kubuntu. Kubuntu already had the symlink /etc/fonts/conf.d/10-sub-pixel-rgb.conf by default, while other flavors had no sub-pixel rule. In 23.04 10-sub- pixel-rgb.conf is default in all flavors. -- You received this bug notification because you are a member of Documentation Packages, which is subscribed to fonts-ubuntu in Ubuntu. https://bugs.launchpad.net/bugs/2017573 Title: Font hinting broken on 23.04 Status in fonts-ubuntu package in Ubuntu: Confirmed Bug description: Just upgraded my laptops to Kubuntu 23.04 Lunar Lobster and hinting for all non-commercial fonts seems broken. I used to have decent if not perfect hinting on Ubuntu and Ubuntu Mono font, but now the only fonts that still hint correctly are Microsoft's Verdana and Tahoma etc. Not sure whether the devide is exactly along this line, but it stands out. Tried regenerating font cache (fc-cache -rv) but that didn't help.
