I attached a small html file: it includes 2 youtube videos embedded in iframes. If I load the page in Chrome and keep refreshing the white box shows up eventually. It has the exact size of one of the two iframes. unity --replace makes it go away. T xwinfo shows something like this (note the window 420x315+0+0):
