Which #freeSoftware does allow #screenSharing (not only viewing, but also keyboard and mouse), between at least Windows and #Linux (either X11 or Wayland, doesn't matter)?
macOS Sarcoma's Screen Sharing has decided that when I connect to my main computer that has two screens, the second screen will be black. In addition, the cursor won't move, and I have to fight to get the insertion point into the password box on the login screen. So yeah, about par for Sarcoma—Apple's flakiest OS in ages.
