Google Chrome becomes slow after viewing web videos

Vedita BR · 04 Nov 2015

Each time i watch a video in Chrome the browser start to behave weird, if i am on the same tab as the video playback and i try to type a word to search or url in URL bar and press enter the browser's loading icon never stops spining and i must close that tab and create a new one and the browser becomes really slow .

My theory is:

A) Internet Download Manager may cause the problem

B) Google Account Sync may slow down the browser ???

C) The Avast online security add-on/plugin browser may is causing the problem

I actually vote for D) the built in Adobe Flash Player

How to fix Flash Player lag in Chrome | Blog

A workaround used to be disabling the built-in and using the same Flash Player as firefox but that no longer works.

Saw this as well:
"To anyone encountering similar issues... try disabling hardware acceleration.... it was a tenfold improvement for me on my laptop.

To disable it... type "chrome:settings" in the address bar, click Advanced Settings, then uncheck "Use hardware acceleration when available" under the System header. Close all open Chrome browser instances and restart Chrome.

Chrome had always ran really well for me.... until rather recently. This seemed to fix my biggest problem of late. Give it a shot and let me know... curious how it works for others. Not sure why HW acceleration seems to be the culprit, nor what exactly changed that caused this issue."
