@lysiol41: Could you please navigate o chrome://settings and create a new profile with no apps and extensions and check if you still face the issue?

Thanks!!

Hi!

So I created brand new profile with no apps and all extensions disabled and I was able to reproduce it without any problems. Can attach video of that later if you want @sandeepkumars

#3, simply use a bigger chunk of text.
For example, select all on this page, copy to clipboard, and use it for step 2.

Also reproducible in 61.0.3155.0.
And even in 53.0.2769.0 (using chrome://md-settings)

chrome://tracing reveals LocalFrameView::paintTree is in progress.
Apparently, it tries to render all that pasted text.
The simplest solution might be to limit the value length to 1000 characters or less.

Can someone from settings team please look into this issue.

Thanks!!

This is similar to  issue 708304 . Also my guess is that it not only happens on settings, but also History and Downloads too.

#7 that seems likely. Also, regardless of how much we optimize text input, more text can be added and we'll eventually buckle. We should consider a limit or accept that not having a limit means we can be overwhelmed. (i.e. the user may add text until it exceeds the available memory swap space and that's intractable).

Issue 832199 has been merged into this issue.

As the opener of 832199, this is really clearly a different issue. The issue I opened occurs with a single paste, with a small amount of text, and occurs in text fields _on_ pages, not the omnibox. Should I re-open the issue or what?

nicklbailey@gmail.com, Thanks for the clarification.

If bug 832199 doesn't have much text pasted then that does sound different. I wasn't clear on the amount of text in 832199. I'll de-dupe these bugs.

Please write a note on bug 832199 with estimates of how long the text is. That will help make it clear that the bugs are different. If the text is dozens or hundreds of characters, that's different from this bug. If the text is 2,000+ characters then it might be the same bug (in which case I'll dupe it again).

Thank you again for using Chrome and entering a bug.
