Thanks for the feedback, @cmderden79! Check out the following post for more details:
Tiles flow from left-to-right, top-to-bottom. So if the browser width is different, the dashboard might be able to fit a different number of tiles in each row and thus the tiles be positioned differently. Judging from the screenshots (which appear to be slightly different crops), the second screenshot is slightly wider than the first and it’s probably just enough room to allow at least one extra tile wide, so the tiles flow slightly differently.
