Description Stefan Cristian Brindusa 2025-01-14 17:32:09 UTC
Fonts are blurry on KDE Plasma 6.2.4 with Wayland and nvidia-drivers-655.77 (was present also in previous version of nvidia).

To note that I have 2 monitors: one is 4K at 144 Hz, and one is 1080 with 165Hz, it's happening on both, and only in this combination: plasma 6.2.4 + wayland + nvidia drivers. It's not happening on Nouveau, nor Gnome.

The workaround solution was to add this in /etc/environment:
FREETYPE_PROPERTIES="cff:no-stem-darkening=0 autofitter:no-stem-darkening=0"

And this reduced the font blurriness significantly up to non-recognizable, so I believe it's a workaround, rather than a solution.

Apologies, it's nvidia-drivers-565.77*.
