Bug: 18203577 The issue occurs as a result of performTraversals() both doing a window relayout call *and* early-returning because it's not dirty. To fix this pauseSurface() returns whether or not the RT-side is "dirty" to force ViewRootImpl to do a draw even if mDirty is otherwise empty. Change-Id: I534f367e75d18d273ebf14df3927f5c464ef6bef
