In the command interpreter (shell) the underline character

then changes to an underline when I hit return and line (2) appears.
Line (2) displays properly.
Works fine here. It might make a difference that I'm using a custom
keymapping, though. Intermittent behavior like that causes me to think
about connections, more hardware than software. If the hardware isn't
corrupted, the software will do the same thing every time with the same
input.
Do you have another app running that might be capturing and altering
X / Wayland keystrokes while you are trying this?
