Playing around a bit more:

1. Start Emacs (scroll-conservatively > 0)
2. Adjust w32 window height (aka EMacs frame) to show (say) 24 rows.
3. Fill *scratch* with with 32 lines of 'abc'

Move cursor to top; down-arrow to end of buffer;
Repeat;

No artifacts

Add 123 as last line of the buffer.
Move cursor to top, down-arrow and etc.

Artifact shows up (almost always) at the end of the buffer.

abc
123

Strange ....
