I've got quicksand set up to sort a list, you can see a demo here (this is a drupal site that I am developing locally, I had to make it a static html page so some things don't look quite right, but you can see the issue):
If you make your browser's width 1090px (on the actual site the issue happens across a much broader range of resolutions, but on this demo it only seems to happen at 1090px exactly - at least in chrome) and click "All" you'll notice that the images all wobble a little bit, when really they should not move at all.
How can I fix this?
