Or, once you can do some actual typing, just type 40 characters on a
line and keep track of whether they appear twice. Especially when you
get close to the right side of the screen, it may be that what you're
typing starts showing up copied on the next line too.

First I had the impression that maybe more or fewer than 40 characters
might be present on a line (that would account for some shifting too).
But I counted one of the pictures and that seems ok (making it even more
mysterious what happens...)
