@mrvanes: I tested with Liberation Sans and Verdana on Ubuntu with GNOME. My notes:
* I can confirm that Verdana honors the font hinting, both on 23.04 and 22.04. * I can confirm that Liberation Sans ignores the font hinting on 23.04. However, I see the very same behavior on 22.04. The difference in rendering between no hinting and full hinting is very small. Please see the attached picture. So the only regression I see is the changed behavior related to the upgrade of the Ubuntu font. It appears to me — as you already have indicated — as if only some fonts honor the font hinting value. But my observations indicate that that is by design. Maybe the default font configuration — antialiasing enabled and only slight hinting — is there for a reason. I'm no longer sure that we have a bug here. :/ ** Attachment added: "hinting-test_liberation-sans.png" https://bugs.launchpad.net/ubuntu/+source/plasma-desktop/+bug/2017573/+attachment/5669194/+files/hinting-test_liberation-sans.png ** No longer affects: plasma-desktop (Ubuntu) ** Summary changed: - Font hinting broken on Plasma 23.04 + Font hinting broken on 23.04 -- 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: New 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.
