What does "paint out of order" mean? I thought WebRender painted everything at once every frame, meaning that there is no order?

Z-order. WebRender can paint back to front or front to back, whichever is best for the situation. This can be tuned.

Couldn't we do that with the old layer system too?

Not as well, because Skia knows nothing about the layers. It can’t do global optimizations.
