Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.89 Safari/537.36 Example URL: https://www.utwente.nl/nieuws/ Steps to reproduce the problem: 1. Open the URL What is the expected behavior? The page should be shown with an animated SVG background overlaid with the page contents on a white background. What went wrong? The page flickers: the animating SVG background pops up to the foreground, obscuring the page content. Google Chrome also starts using a lot more CPU power (on my MacBook around 60%). If I delete the SVG layer from the page (the <div> with class "header__backgrounduniverse"), it behaves normally again and the CPU usage drops significantly (on my MacBook to around less than 1%). Does it occur on multiple sites: Yes Is it a problem with a plugin? N/A Did this work before? Yes I only started seeing this behavior after updating Chrome from version 52 to version 53 Does this work in other browsers? Yes Chrome version: 53.0.2785.89 Channel: stable OS Version: OS X 10.11.6 Flash Version: Shockwave Flash 22.0 r0 I thought it might be a hardware acceleration problem, but I still see this behavior when I disable hardware acceleration in the settings. A colleague of mine also sees this behavior, but others can't (all using Chrome 53 on a MacBook with an Intel 3000 video card)

I can reproduce it on a Mid2011 13" Macbook Air, with Intel HD Graphics 3000 384MB On this machine, the problem occurs when an external HD monitor is plugged in, but I can't reproduce it with only the internal display enabled.

It's a late 2011 13 inch MacBook Pro with a 2,4 GHz Intel Core i5 processor, 16 GB 1333 MHz DDR3 memory and an Intel HD-video 3000 512 MB video card running OS X El Capitan (version 10.11.6)

I have not been able to reproduce it at all on my early 2011 15" macbook pro, with either the dedicated AMD Radeon HD 6750M 1024 MB or when I force it to the builtin "Intel HD Graphics 3000 512 MB"

Since I reported the bug I've updated my Chrome browser to version 53.0.2785.116 and I can no longer reproduce this myself. Maybe something has changed in one of the intermediate releases that fixed it. I will ask my colleague to check it on his machine as well; if he cannot reproduce it either, I think the bug may be closed.

It turns out I can still see the effect, and my colleague sees it as well, so it doesn't seem to be fixed after all...

Are the issues found only on one class of machines (i.e. the same model of Mac)? We have seen issues in the past related to incorrect stacking of content on specific Mac machines.= and this seems similar.

They're all 2011 macbooks, although one's early 2011, one's late, and one's an air. I'm seeing a lot of other odd things happening in Chrome since the last update... a lot of flicker where the SVG backgrounds shortly shine through, mostly during scroll but even stationary... tabs which go completely white, or black with some white squares, mostly after coming out of sleep but requiring a chrome restart to fix... But that's just this early 2011 book, haven't heard this from the other books. A few of the tabs were running the SVG-animating-background this issue is about, but the white tabs were on different sites. Some part of the graphics stack seems very confused on my machine in Chrome, but it's hard to properly reproduce it and create a proper issue out of it.
