Comment on attachment 226526 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=226526&action=review > Source/WebCore/page/FrameView.cpp:1542 > + viewportRect.setLocation(LayoutPoint() + scrollOffsetForFixedPosition()); Just out of curiosity, why is this better than toLayoutPoint() ?
