Wayland forwards the raw keycodes (meaning ESC is 1, 1 is 2, 2 is 3, etc...), while X11 forwards them with a constant +8 offset. This is apparently something known about keymap handling:

See the xkbcommon documentation:

Note that in all current keymaps there's a constant offset of 8 (for historical reasons).

What should we do to be consistent?

• Should the wayland backend add the +8 offset?
• Should the X11 backend remove it?

Is there a way we can compare to the other backends?
