I can't reproduce this. If I don't click wildly on the scroll bat at the time the clear screen action takes place (so I move the window right after clear screen), the cursor is positioned at the top of the screen, at the end of the buffer. So, how would I reproduce your observation so that all window positioning is guaranteed to take place *before* the clear screen action and still see the broken output?
