It almost sounds as if you have the wrong terminal type selected, so that the
code emacs sends to clear the screen isn't.

Like suggested, start emacs with 'emacs -Q'.

Then start a shell in emacs, and see what your terminal type is set to...

For example, when I start a shell, and type  echo $TERM, I get 'dumb', and it
all works fine.

Let us know.
