Wayland Protocols 1.31 Released With Fractional Scaling Support
The Wayland fractional scaling protocol "wp-fractional-scale-v1" has been added as a new staging protocol. The Wayland fractional scaling support allows the compositor to communicate a scale for more precision compared to integer-based scaling.
More details in the Phoronix article a few days ago around Wayland fractional scaling. With this v1.31 release, the initial staging protocol is finally in place. There are implementations pending for the likes of Sway / wlroots, GNOME Mutter, KDE KWin, and other compositors.
See the release announcement for the list of the few other changes making up the wayland-protocols 1.31 release.
