I had a look in a Kubuntu 23.04 install I have in a VM, and it looks like changes via the KDE UI for managing fonts alters the file ~/.fonts.conf. If that is the way you do it, can you please attach your ~/.fonts.conf file to this bug report.
The ~/.fonts-conf file has been considered deprecated for quite a while. I wonder if they possibly have stopped to read that file now, which would explain your observation. Otherwise, if ~/.fonts.conf still is a valid place for fontconfig rules, it might be a Plasma issue... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/2017573 Title: Font hinting broken on 23.04 Status in fontconfig package in Ubuntu: Incomplete 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.
