Textarea Pasing Text Lag

Reported by dillybo...@gmail.com, Mar 14 2016

Issue description

<b>Chrome Version       : <Copy from: 'about:version'></b>
URLs (if applicable) :
Other browsers tested:
  Add OK or FAIL, along with the version, after other browsers where you
have tested this issue:
     Safari:
    Firefox:
         IE:

What steps will reproduce the problem?
(1) Copy text and hold down ctrl+v in a textarea field
(2) The textarea field has to be created by document.createElement to replicate this bug

What is the expected result?
Browser's FPS drops to 1, and the browser freezes dependent on the duration of the CTRL+V keypress

What happens instead?


 

 
Edit: The textarea element actually doesn't' need to be created by document.createElement, it can be in any textarea (even the comment box I'm posting on now)

Thanks for the report. Request you to please provide a sample jsfiddle or html file which will replicate the above issue ? Also, let us know the OS details and chrome version details on which you are facing the above issue.

I really appreciate the help.

Thank you!
Hey Asheljole,

https://jsfiddle.net/Lkefn1jc/

Here is the jsfiddle.

Basically copy some text and start pasting it into the text area and hold down CTRL+V, after a few seconds chrome will freeze up and the main thread will be locked up (lag out).


Windows 7, Prof 64-bit

And Chrome version: Version 49.0.2623.87 m
This doesn't happen on IE, Firefox, Opera, or other browsers by the way. If you create the textarea by document.createElement('textarea'), it will freeze up faster (what I have noticed).

The above issue is reproducible on All-OS (Windows (10 & 7), Mac 10.11.4 & Ubuntu 14.04) with chrome versions : 50.0.2661.87(Stable), 51.0.2704.22(Beta) & 52.0.2717.0(Canary).

This is a non regression issue as can be seen from M30 build - 30.0.1549.0. Hence marking the same as Untriaged.

Thank you!
