You'll see white gaps appear between table rows occasionally. I can reproduce this most reliably by two-finger scrolling on a trackpad, but it's also possible to reproduce this issue when scrolling with either the scrollbar or the keyboard. The border-collapse:collapse is not an essential part of the test, it just makes the underpainting stand out more visibly.
