Moreover, the frame size after evaluating the
create-fontset-from-ascii-font form is odd, so "C-x 3" cannot possibly
create 2 windows of the same width.  And that is what you see: one
window has one pixel more in its width, so we show the corresponding
part of the cursor.  I don't see anything wrong with that.
