@marcan yeah ... the fractional scaling Implementation in GNOME is really sad and broken 😞 we wanted to enable it by default for Fedora 39 but it turned out to break rendering of Xwayland applications, *always* upscaling from 1x, even on "integer" factors ... (side effect: fullscreen applications like games only "see" a scaled framebuffer so they can't even render at full resolution if you wanted)
the "let xwayland windows scale themselves" option in KDE is not perfect, but much better 😐
