Jason Rumney suggseted this may be a Windows bug. Well I've got
a bit more info which may help to find out.

I can now repeat this very easily. The redraw goes wrong for
any partially covered window if the bit that is covered has
a larger font in it.

First, to be able to scroll the window at the back you must
have X-mouse enabled (focus follows mouse)

Then if you create a buffer in Fundamental-mode, put some text
in it, select a line of text and change its text property
to Info-title-2-face (M-g o Info-title-2-face)

Now partially cover the window with another one and scroll the
window at the back. I usually use the mouse wheel, but the
keyboard does it aswell. You will see as you scroll up (text
moves down) that part of the covering window moves down.

HTH
