Comment on attachment 254121 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=254121&action=review LGTM. However it would be nicer if you write description more detailed as I comment. > Source/WebCore/ChangeLog:13 > + (WebCore::CoordinatedGraphicsLayer::didUpdateTileBuffers): Please add "Added" for didUpdateTileBuffers(). > Source/WebCore/ChangeLog:16 > + (WebCore::CoordinatedGraphicsLayer::tiledBackingStoreBackgroundColor): Deleted. It would be good if you write that "tiledBackingStoreBackgroundColor() is not used anywhere." > Source/WebCore/ChangeLog:19 > + (WebCore::CoordinatedTile::updateBackBuffer): Please write what is changed and why do you modify.
