Comment (by iammattthomas):

 The sidebar needs to be set to display: none by default for small screens,
 and display: block when the .wp-responsive-open class is set. This
 eliminates the flash of the standard sidebar when switching between
 portrait and layout on a tablet, or when resizing a desktop browser
 window. It also eliminates the flash of the sidebar on Windows Phone 8
 devices. Because we're now setting the display property, the transition
 has no effect, so it can be removed. This eliminates quite a bit of the
 jankiness on mobile devices and speeds up the performance of the sidebar.
