Your scrolling premier release changes height sometimes depending on your screen width. Which means that while you are looking through the list of items on the page, they shift up or down a row depending on how many rows are in that top set. Sometimes today, it was 1 row and then it would shift to two pushing things up and down depending. It's bad enough that I just close the window after it happens a few times which probably limits my exposure to new items that may have been of interest to me. I seriously doubt I'm the only one.
