I see some nice performance & power wins with picture caching enabled on Mac.
e.g. 

scrolling arstechnica.com:-  
   picture caching off ~45 fps; 14 ms GPU time, picture caching on ~60 fps; 9 ms GPU time.

leaving the small throbber onscreen from https://bugzilla.mozilla.org/attachment.cgi?id=8962814 :-
   WR off, 2 W CPU + 4 W GPU, total processor package uses 9 W 
   WR on caching off, 1.5 W CPU + 8 W GPU, total processor package 12 W
   WR on caching on, 1.5 W CPU + 2 W GPU , total processor package uses 5 W

Nice! Thanks.

Now that this is landed and enabled by default, should we close the meta and track bugs individually? Or is it best to leave this open for now?

Let's close it.
