Edit LayoutTests/compositing/iframes/resources/fixed-position-subframe.html and remove "overflow:hidden;".
Run LayoutTests/compositing/iframes/fixed-position-iframe.html with run-minibrowser on Mac.
Resize the window so that only green is showing.

Scroll the subframe down, then up.  You will see a red blip at the top where you can see the results of a scroll prior to the iframe being repainted.  If the iframe were repainted prior to scroll, the background red color shouldn't be shown at all.
