The more I look at your screenshots, the more it looks to me as if
some cursor addressing commands in x coordinate direction are not
obeyed by the terminal emulator.

For example, the one where the echo area shows this:

  Write current buffer to another file    Re-read current buffer from its

It is quite clear that this happened because the second help-echo, the
one on the right, was written starting at the x-coordinate where menu
ends, and not at x = 0, as it should have.

Or take this:

  --                                      --
  Print Buffer

where both the leftmost "--" and "Print Buffer" have red background.
Here, instead of overwriting the red-background "--" with the
blue-background "--", the terminal drew the latter starting where the
menu ends, i.e. again at the wrong x-coordinate.

Etc., etc.

The question is: how come the same terminal obeys those same commands
when they are re-played (perhaps more slowly) later?

Could some termcap/terminfo specialist please help figure this out?
