@MTVTeam-- Could someone from MTV team look into this , as inhouse-team doesn't have the Touch MacBook.

Thanks!

I can't repro it, but I saw some user feedback online.

I'm pretty sure the cause is the touch bar being invalidated in each page load.
I'll see if there's an alternative

 Issue 749262  has been merged into this issue.

tomalo.stuttgart@gmail.com - can you provide the URL of a site that reproduces the problem? Also, can you provide a movie that shows the flickering (e.g. using your phone to record it)?

Video of flickering on THIS page:
https://drive.google.com/open?id=0B56TFlHGg9mVTWgwajY3Mk94Tnc
Tried to attach it, but got the request too large error.
So, what is really strange, is that for a couple of days everything seemed to work fine, but here it is again. WTF?

Thanks for the video! It's a strange error, and it's especially strange that the search button is the only one affected. I'm experimenting with several different things and hopefully will be able to come up with something soon.

Have the bug also. (https://twitter.com/jnybgr/status/895636912245026817)

It seems like the flickering only happens when a network request is active, I suspect at least. Either manual reload / navigation or when something is loading on the page via AJAX makes it flicker. 

Thanks for the info, it's helpful for the investigation! The issue is that whenever the navigation status is changed, the stop/reload item gets updated to reflect that, which ends up invalidating the entire touch bar. 

I also noticed that in your tweet, you mentioned that you can't turn it off and it's bothering you. Until a solution is landed, you can remove the search button from the touch bar by going to View > Customize Touch Bar. Hope this helps!

Oh yeah, thank you! That works for the moment.  I'm actually going to delete my tweet then. 

It seems that re-arrange the position of touchbar elements in chrome is a temporarilly workaround. I placed the "new tab" button on the left hand of search button (removed search button before and reset it to default position) and till now it works for me.

Update. Flickering is back :(

Quick question, if you remove all of the other elements and just leave the search button there, is the flickering still there? I want to check if it has anything to do with the layout (since the search button has different layout constraints)

I'm unable to reproduce this issue on my machines so this information will be helpful. Thanks!

I compressed the video for posterity.

[Mac] Remove Excessive Touch Bar Invalidates

The touch bar is updated with every page load, so that
the stop/reload button would have the proper state.

However, this causes the search button to blink frequently
in some hardware. To fix this issue, remove the excessive
invalidates and update the stop/reload item independently.

Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch ASAP. Thank you!

Know that this issue shouldn't block the release?  Remove the ReleaseBlock-Stable label or move to M62.

I was unable to reproduce the issue on the latest beta(61.0.3163.39- which as per this issue should show the buggy behavior) using MacBook pro 10.12.6 Touchbar. Attached is the configuration this was tested with.

Requesting someone who were seeing this issue for help in verification on canary. You can download the canary from here: https://www.google.com/chrome/browser/canary.html

+ajha@, could you pls verify this bug on Canary?

This issue doesn't seem to repro on the available Mac touchbar laptop on the build with and without fix. Hence unable to verify this.

Yes it's critical since it might fix an annoying bug with the Touch Bar. I tested it throughly, the risk is low
