Multiple windows severely degrades performance

Reported by pbsc...@gmail.com, Mar 20 2016 
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36

Steps to reproduce the problem:
Open multiple windows

What is the expected behavior?
The newly created windows will have the same performance as the original one

What went wrong?
The original window will stay snappy (visible whilst scrolling up and down fast) but the newly spawned windows will be visibly slow even on non-graphic intensive websites like Wikipedia to scroll up and down. Whilst scrolling CPU-usage also goes through the roof (uses 2 of my 4 cores at almost 100%). Rejoining the windows by dragging the tab onto the original window will restore performance to the tab

Did this work before? Yes Not sure, but I believe v48 did not have this problem

Chrome version: 49.0.2623.87  Channel: stable
OS Version: 4.4.5
Flash Version: None

Unable to reproduce the issue for chrome stable version 50.0.2661.94 on Ubuntu 14.04. Created multiple windows of chrome and did not observe and performance degradation.

@ pbscube: Request you to please try a system restart, update chrome to the latest stable available and try again. Please update us with your observations.

Thanks.!

Thanks for the feedback - I now released that this has stopped occurring on my pc, I have a suspicion that it might be a problem with my graphics driver (proprietary Nvidia) since I now downgraded to v49 110 and the problem seemed to have disappeared on that version also (The problem did occur there some time ago). Chromium is the only graphical application I use on my pc so this could've very well happened on other applications too but I can't verify this. Thanks for coming back to me sorry for the trouble
