I paid more attention today and noticed that droppings only appear if,
for some reason unknown to me, the cursor block disappears.  After that,
even moving the cursor with h-j-k-l leaves a trail.

I can't imagine why the cursor should disappear, but it does.  One of the
vagaries of WinBlows, I suppose.
