TileList flickers on new items

Hi, im adding a series of images with labels to a TileList and every time an image is added - all the previous images flicker (hide for one or a few frames). The labels do not flicker. Since there is a slight delay between adding the individual images theres a whole lot of flickering going on. Any idea how to solve this? Can i perhaps force the old list items not to redraw or something? Neither livedocs nor google is helping

Adding with this code:

tilelist.addItem({label:"imageXX", source:"imageXX.jpg"});

Any help appreciated

edit: btw the images are absolute web paths from another server, might that be it?
