Ubuntu’s font rendering used to be better than every other distro, because they incorporated patches on freetype that were legally ‘iffy’ as to whether they infringed on microsoft’s patents; later whatever exclusivity requirement that there was with those patents expired, and the patches got upstreamed in freetype itself.
So now all Linux desktops are capable of subpixel font rendering, hinting, whatever. But before that, font rendering really was hideous on other distros.
I don’t think it does virtual desktops with labwc still; but when it does, labwc is as good a replacement for xfwm as any, IMHO.
labwc can do virtual desktops; there’s a desktop switcher, and the window switcher is aware of windows only in the current desktop – but I can’t figure out how to query window-per-desktop information programmatically otherwise. waybar, wlrctl, as well as xfce-panel don’t seem to have access to that info either. Still waiting for accomodations with respect to some wayland extension, I suppose.
