I too have a scrolling bug/issue with your capx, when I scroll weird items appear and disappear, very similar to what you have on your youtube screen capture.
When I move things around, its seems that there is some kind of shadow of them to the right that moves along. The text is beside the boxes, just like you have on your vid.
I am on Windows 7 64 bit, have a GTX Geforce 960 card and its drivers are up to date.
