Log Message
In background window, page flashes white if it enters and then immediately leaves compositing mode
https://bugs.webkit.org/show_bug.cgi?id=69566
<rdar://problem/9521192>
Reviewed by Dan Bernstein.
Don't update the backing store state if we're just about to exit accelerated compositing mode. Otherwise
the UI process will try to render an empty layer tree for a short period of time, leading to a white flash.
* WebProcess/WebPage/DrawingAreaImpl.cpp:
