Created attachment 183909 [details] Adwaita Sans font SUMMARY I'm unsure if this is Qt bug, Freetype bug or KDE bug... Anyway, when using Adwaita Sans font, it looks oddly blurry with bold weight. However, regular Inter font looks fine. STEPS TO REPRODUCE 1. Install Adwaita Sans font 2. Set it as your font OBSERVED RESULT Anything bold looks weird EXPECTED RESULT Anything bold would look same as the Inter SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 KDE Plasma Version: 6.4.80 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.1 Kernel Version: 6.15.9-201.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 16 GiB of RAM (15.5 GiB usable) Graphics Processor: AMD Radeon RX 6600 ADDITIONAL INFORMATION There was already prior bugreport in GNOME bug tracker here: https://gitlab.gnome.org/GNOME/adwaita-fonts/-/issues/2

I tried to see if setting following to /etc/environment would have any effect: ``` FREETYPE_PROPERTIES="cff:no-stem-darkening=0 autofitter:no-stem-darkening=0" ``` or ``` FREETYPE_PROPERTIES="cff:no-stem-darkening=1 autofitter:no-stem-darkening=1" ``` However with stem-darkening off it got significantly worse (a lot more jagged), so it's not that at least.
Created attachment 183912 [details] Empty font weight I made another report for this in here: https://gitlab.gnome.org/GNOME/adwaita-fonts/-/issues/21 It might be a bug in the inter font itself. Unsure. But we should definitely ignore the empty font weight like shown in the image.
It's definitely not a KDE bug, as we don't do anything with font rendering. It's a Qt bug, a FreeType bug, a FontConfig bug or distro-specific misconfiguration, or a bug in the font itself interacting with any of the above.
