First type some short command, then type a long command, then use up and down or page up and page down key, server will send back stream characters with many '\x1b[C' chars, feed those data and call screen.display, the result is not correct.
Could you provide a reproducer please? Are you driving the Screen manually or from a pty?
From pty.
I have below output, use debug screen,last command is ["draw", ["eeeeee"], {}], but when I print the screen.display, the result is cccccccccccccccccccccccccccccccceeeeee
output:
