On Fennec for Android, when the window size changes we see a black flash before things are repainted. Then everything reflows. This is really bad perceived performance. Ideally we'd preserve the old image until new content has been reflowed and painted, even if it takes a little longer to get things in order.

This seems to only happen on Android, specifically when virtual keyboard comes up.

STR 1: focus text box in url screen
Sometimes, in latest nightlies, the black will stay until you press back or tap text box (or where you think the text box is).

STR 2: tap on input box on news.google.com
