Jeff, I couldn't reproduce.

I think it's possibly related to the graphics card or similar, not being able to display the notes in the given time. The notation view is busy rendering the next bars on the LHS of the screen at that time.

I'm seeing red notes on 7(3), 8(3), 11(3) and 12(3).

Try lowering the tempo to say 100, and see if the situation remains. That might be a good way to prove.

Incidentally, my display was set to 4 bars per screen, and I recorded the two at the right, these are the ones you are having problems with.
