I have a folder with thousands of photo on it. Every time I enter the folder (even in the same Gnome session) Nautilus start showing the icons (thumbnails) for that folder but the listing is very slow. Furthermore, the window's vertical bar, moves and shriks as the list grows, so every time I have to wait for the list to finish before I can comfortably scroll up and down my pictures. Why does this happen ?
Note: it is not a matter of thumbnails rebuild since if I scroll down the bar last images icons are displayed properly.
