Scrolling example

This is actually by design.  The low-quality resize is always done first, since even scrolling may be affected by the speed of high-quality resize.  For example, I've attached a static page, which when scrolled, shows very poor scrolling performance without my fix (these are all the same image, of course, but it would also happen for many small thumbnails of different images).

If this new behaviour is still not acceptable to you, I do have an idea for a fix which will preserve most of the performance gains of the original fix.  It will definitely regress on pages like the attached, however.
