Also occurs on 55.0.2883.21 beta-m (64-bit)

Able to reproduce the issue on Windows-10, Ubuntu 14.04 and Mac OS 10.12 using chrome latest stable M54-54.0.2840.71 by following steps mentioned in the original comment. Observed typing some text in the text area takes time to reflect.

Unable to perform tool bisect due to different issue observed on chrome M53 builds. For example if I try to repro this issue using same above steps on chrome #53.0.2756.0 the forum page completely goes blank and no contents are seen.

Considering the above behavior as bad, I have narrowed down good and bad builds and providing manual CL below as per omahaproxy.

https://chromium.googlesource.com/chromium/src/+log/53.0.2754.0..53.0.2756.0?pretty=fuller&n=10000

Could anyone look in to this and help us in assigning to the concerned owner for further triaging.

Thanks!

+Laura, can you help us find an owner for this?

Removing Extensions label for now so that the accessibility team can have a look to see if this is just the extension doing something inefficient; feel free to relabel if this seems to be a bug in the extensions platform itself. 

I have the exactly same problem.

After I enable "high contrast", my gmail is frozen. Other website with input box also become frozen.

After I disable "high contrast", gmail and other websites become normal immediately.

I am using Dell Latitude E7440, and Windows 7 operating systems.

I used gmail and high contrast daily. It worked fine until yesterday, 10/27/2016. 

I first found that gmail became frozen. I re-installed Chrome. Gmail works fine again. After I enable "high contrast", then gmail becomes frozen. After I disable "high contrast", gmail works again. So, the root reason is "high contrast".

Hope Google can fix it soon. Thanks.

Issue 661190 has been merged into this issue.

Same issue here. Ironically, it's primarily a problem with google web pages (docs, specifically for me.) Google assures me they are working on it :) 

Routing to blink team for triaging, from the console error it seems to be bilnk-css issue.

Can someone bisect and check whether the errors in #10 are also present in versions of Chrome where this works as intended?

As per comment #11, Checked the errors in Windows-Chrome good build version-50.0.2640.0 & observed different errors unlike errors shown in comment#10.

Here i am attaching the good build & bad build error screenshots for your reference.

Ligimole@ Please let us know if anything needs to be done from our end.

Thank you.

Given when users started to report this issue, I think there's a good chance this is the same issue as 661190.

Can you try the original repro to see if there's a difference between these versions?

Thanks !

 Issue 662969  has been merged into this issue.

Bisecting  bug 662969  led me to the same patch (r415043), and also r395263, also by @senorblanco

Bug 661190 seems related too

I've pushed a new version of the High Contrast extension with a workaround to the web store.

Can anyone confirm this fixes the issue for them? I tested it manually and the workaround seems to solve the problem. Visit your extensions page and manually refresh. The updated version of High Contrast is 0.9.3.

If verified, we can remove the releaseblock but keep the bug assigned to @senorblanco because the underlying issue with CSS filters may affect other sites too.

Just installed the updated extension, and it seems to have fixed the problem for me. Thanks.

Verified this issue on chrome latest M55-55.0.2883.44 by following steps mentioned in the original comment. Observed no performance lag while typing when high contrast extension is enabled in chrome. Hence adding TE-Verified label.

Removing "ReleaseBlock-Stable" label based on comment #17 and #19.

The Blink>CSS component has a policy of one component per bug. It's not clear that this bug belongs under Blink>CSS. I'll remain cc'd in case you need the attention of the Style team.

Hey Victor - can you help triage? I don't know Chrome well enough to tell if this is Skia, renderer or something completely different.

This issue sounds fixed based on comments #17 and #19.

dmazzoni@, what workaround was required to fix this and how can we reproduce the original issue?

Assigning to senorblanco@ to weigh in on the underlying CSS filter performance issue.
