I love the options given by the Parallax effect, but it seems to have an issue that the position of the images seems to change when the user scrolls several times.
For example, here's roughly where I want the images to align
After scrolling up and down past them several times the images are now aligned completely differently, and actually has "jumped" down to the next row.
The issue seems to be accentuated if the scrolling is done more quickly.
