I can reproduce this easily in the latest nightly build by resizing the window to be relatively short, giving lots of room for scrolling, scrolling to the bottom of the page, and then slowly scrolling back up. The bottoms of <select> elements and buttons are not correctly painted. This doesn't appear to happen in Safari 4.0.3.
