When scrolling down a page with text in it using the down or up arrows miscellaneous charracters are elevated above the others (the vertical registration is wrong). The random character elevation occurs every other tap of the up or down arrow. Using a touch interface or grabbing the scroll bar does not seem to have this problem.
