Comment on attachment 388934 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=388934&action=review > Source/WebKit/UIProcess/API/Cocoa/WKWebViewPrivate.h:518 > +@property (nonatomic, readwrite, setter=_setClipsToVisibleRect:) BOOL _clipsToVisibleRect WK_API_AVAILABLE(macos(WK_MAC_TBA)); Please add some explanatory comment in header doc style. I would suggest: _clipsToVisibleRect: When YES, the view will use its -visibleRect when determining which areas of the WKWebView to draw. This may improve performance for large WKWebViews which are mostly clipped out by enclosing views. Should we make this available for iOS too?

The boolean value this sets is only used inside of #if PLATFORM(MAC). If requested, we could develop a conceptual equivalent, but this is sufficient for now.
