I've seen similar behaviour a few days ago while running a macro. It 
seems to occur at some points when the window scrolls (but not others), 
and in my case I don't think any wrapped lines were involved (maybe they 
were temporarily during the macro running, I'll have to try to recreate 
the situation to check).
