The size of scrollbar arrow button returned by ScrollbarThemeChromiumWin::buttonSize is not correct on Windows. For Linux, ScrollbarThemeChromiumLinux::buttonSize in WebCore is actually delegated to getSize on NativeTheme instance. For Android, because the scrollbar arrow button is painted by threaded compositor, buttonSize returns hard-coded value (0, 0) directly. Since the theme framework built upon NativeTheme class hierarchy, for AURA theme, we don't draw scrollbar button which requires that the button size should be a empty rectangle. However, there is no way for aura theme to get the correct button size in WebCore level. Reference http://code.google.com/p/chromium/issues/detail?id=130856 for a bug in chromium caused by it.
