Comment (by Thorin):

 The white element is YT using a canvas element, which RFP renders white

 Obviously one solution, is to allow canvas on YT: but that defeats the
 purpose - and it wouldn't surprise me that the reason for doing this is to
 force users to remove privacy protections. The fact that canvas RFP
 protection is easily detectable can be used against users

 Another solution is to play whack-a-mole with JS/elements: and that's not
 a long term solution either

 Tom's ticket on poisoning canvas is probably the ultimate answer
