Comment on attachment 432690 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=432690&action=review Very nice investigation and work. r+ with one small comment. > Source/WebCore/platform/graphics/cocoa/GraphicsContextGLOpenGLCocoa.mm:271 > + // WebGL requires that all resources are cleared at creation. Could you add a comment here that performing robust resource initialization in the VideoTextureCopier adds a large amount of overhead?
