This behavior is not a bug in itself, it's just a symptom: it means that
redisplay was interrupted by user input before it had time
to terminate.  See redisplay-dont-pause.

So, the problem you're reporting is that Emacs's redisplay is too slow
to keep up with the scrolling (which is indeed a problem).  This may of
course depend on the file's content and the major-mode (since part of the
redisplay time might be used by font-locking, for example).
