I see this too. It does not always happen, but when it does, that terminal will remain affected. Doing a visual bell (terminal flash) will clean up the corruption, but then I can trigger it again by having something write a lot to the terminal, and the scrolling will get corrupted. If I close that terminal and open a new one, it generally stays gone. Not sure what initially triggers it.
