Description Ryosuke Niwa 2013-12-16 14:43:03 PST 
Consider merging https://chromium.googlesource.com/chromium/blink/+/3b9e71135ee5f6bfe19581a4b19790cde588bd2c
if it's applicable to WebKit.

The problem seems to be the creation of a transparency layer while
painting the background. The solution is to prevent any form of isolation
caused by blending when painting the root element.

This issue is related to mix-blend-mode for software, which isn't currently implemented in WebKit. Since it's not applicable to WebKit,  we should probably close this

Chromium specific issue.
