re-render it to display it again. It's as though Memory Usage is set to Low instead of Normal or Aggressive, but the setting makes no difference. This is very inconvenient in cases where it takes more than a fraction of a second to render a page, which is the case with most of the PDFs I use.
I tested this on TDE 13.2 and saw that the default behavior is to start the new page with a scaled thumbnail and then to render. You have to scroll quickly to see this.
