[Pkg-chromium-maint] Bug#831445: chromium: Some web pages use 100% cpu all the time

[Ara Keary]

Package: chromium
Version: 51.0.2704.79-1
Severity: normal

Dear maintainer,

i've noticed some web pages, such as

http://www.nationalgeographic.com/photography/photo-of-the-day/2016/7/sri-
lanka-tree-scene/

http://www.nationalgeographic.com/photography/photo-of-the-day/2016/7/hussaini-
bridge-pakistan/

use 100% of cpu, all the time, even when the tab is hidden.

This happens with all plugins/extensions removed or not, in incognito or not.
With flashblock or not.
With adblock or not.

Under firefox, the page goes at high cpu during loading, but then goes back to
normal.

I don't know how to identify which component takes so much cpu, but it seems
strange that a "normal" web page uses 100% of a cpu thread all the time.

Best,
Ara
