Yeah, that's a new one I haven't heard about before.
Try changing view between "normal", "replay", "extended", etc...
But when you change between the views - hit the RESTART - not just rewind in the playback. click on the one that says restart the replay from the beginning.
The boxes (in my above post) that appeared in the track... I could only see htem rise up ONCE, then I had to restart the replay from the beginning. Otherwise, if I just hit the rewind, they would just already be there laying in the track.
So there is definitely something hinky with that rewind... Just like hte accident pics I also posted earlier in the thread... where if you hit rewind, you can see the smoke & the skid marks on the track before the accident occurs.
