<a data-role='button' data-iconpos='notext'></a> generates a nice, circular button suitable for all kinds of widgets. Unfortunately, the span.ui-btn-inner inside the anchor adds a 1px white border, which becomes compressed to the top of the button, causing a white line to be tangent to the button at the top.

This line is visible with multiple swatches (tried a, c, and e)
