(Whiteboard: [wr-reserve]) 

This causes a lot of battery usage
So this happens without webrender, but we end up using a lot more CPU with WebRender.
Summary: Huffingtonpost continuosly repaints → Huffingtonpost continuously repaints using more CPU than without WebRender
Nightly 58 x64 20171104100412 de_DE @ Debian Testing (KDE, Radeon RX480)
fresh profile: layers.acceleration.force-enabled, gfx.webrender.enabled, gfx.webrender.blob-images, gfx.webrender.debug.profiler

After I removed every iframe near/from "AdChoices" and the left video under TOP VIDEOS (it was an iframe with a loading circle), gfx.webrender.debug.profiler got quiet. One Ad probably had canvas and promoted a game: It presented different advertising messages over an animated background and a button at the end.

(Btw, the "GPU" diagram & stats below "DisplayList IPC" seem to be completely dead.)
