(Keywords: nightly-community, Whiteboard: [gfx-noted]) 

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20171026100047

Steps to reproduce:

turn on gfx.webrender.enabled
turn on gfx.webrender.blob-images
turn on layers.acceleration.force-enabled

1. Navigate to https://about.me/mattiamaestrini
2. (Optional) Select "MATTIA MAESTRINI"


Actual results:

Very high CPU use, fans spin up as soon as page loads.

Text selection is extremely slow (selection takes seconds before highlight appears when dragging across text).


Expected results:

Same behavior as when WebRender is not enabled.
Nightly 58 x64 20171026100047 de_DE @ Debian Testing (KDE, Radeon RX480, AMD FX(tm)-8150 Eight-Core Processor)
fresh profile: layers.acceleration.force-enabled, gfx.webrender.enabled (also tested: + gfx.webrender.blob-images)

Can't reproduce, everything is fast.
ksysguard shows firefox 2% + Web 1% for ca. 1 second. Afterwards, the "CPU %" column is empty again (=too low).

Can confirm this page basically locks up my entire machine on macos. Subsequent visits lock up without doing anything at all.
