My Wacom-based touchscreen works fine in X with only libinput installed. In Wayland, the touchscreen, stylus and all other features are completely unresponsive. I found complaints a few years old that this was a known defect. However, references to it in https://community.kde.org/Plasma/Wayland_Showstoppers have been removed.
Is it still known to be broken or have I not set it up correctly? I can find plenty of information about setting up tablets in X, but not on Wayland or with libinput. Guidance would be much appreciated if it's possible.
