I am not very clear what you mean by, not aligned in the top? Do you
mean that the cursor is not at the last prompt after you have evaluated
your commands?

If so, then this could happen occasionally. I have spent literally days
hunting this problem. It is something very deep in emacs and relates to
how emacs re-displays its frames. And when it does that it also resets
the prompt position. I don't have a reliable way to reproduce this, but
it often happens on long tasks that print something from time to
time. At some point the cursor jumps from eob, where it supposed to
stay, to the center of the window.

What you can do, is to set comint-scroll-to-bottom-on-output to the
value you want. That solves the problem but creates other inconveniences
that might be, or not, important to you.
