Chrome V61.0.3163.100 takes huge amounts of CPU

Reported by nirbenel...@gmail.com, Sep 24 2017 
UserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.78 Safari/537.36

Steps to reproduce the problem:
1. Install Chrome V61.0.3163.100
2. Open the browser.
3. Observe CPU consumption, especially when opening tabs and switching between tabs

What is the expected behavior?
Opening tabs and switching between tabs should occur seamlessly and quickly.

What went wrong?
There's a 1-2 seconds lag when opening or switching between tabs. On the background, a high CPU consumption is observed.

Did this work before? Yes V60

Chrome version: 60.0.3112.78  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 61.0.3163.100

I had to uninstall V61 and reinstall V60, which immediately resolved the problem.

I've been using Google products for years, this has never happened in the past. I'd be happy to assist you in debugging to make chrome better, please feel free to contact me for further information.

Unable to reproduce this issue on Windows-10 using chrome latest stable #61.0.3163.100 by following steps mentioned below.

1. Opened chrome and navigated to different webpages
2. Pressed Ctrl+Tab to switch between the tabs
3. Observed less cpu usage in chrome task manager and able to switch between tabs with out any delay.

Reporter@ Are you able to reproduce this issue on incognito mode as well? Please recheck this issue by creating a new profile under chrome://settings with no apps or extensions in your browser. Attaching screen cast for reference, please take a look and let me know if any steps is missing from my end.

Thanks!
