Mango/IE9: refresh problem ?

Hi,

Having used Mango for a few days now, I discovered some annoying refresh problems. It seems than when scrolling to a new part of a website, the screen isn't refreshed yet. Only after a a few ms (up to 1 sec sometimes), the site appears. It doesn't seem to appear in every website, and the delay vary as well, but it's really annoying.

Note that this happens after the website has finished loading.

I've seen this to seams to be worse after you pinch and zoom in. It is a tad annoying but that's it.

it seems to happen to me everytime I start scrolling a page before it's finished loading or when I hit start to do something else in the meantime and then go back to the page, in other occasions it doesn't do it to me.
