Images are not shown correctly on calibrated monitor

Reported by sven.jen...@gmail.com, Oct 10 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Example URL:
https://picload.org/view/dgircpaw/fehlerhafte_darstellung.jpg.html

Steps to reproduce the problem:
1. Open a website with Chrome on a system with monitor color profile. 
2. Scrolling on a wide gamut display shows flickering colors.
3. 

What is the expected behavior?
Colors of images on websites should be shown like in Photoshop or Windows Image Gallery.

What went wrong?
The colors of websites and images look wrong in Chrome. On a wide gamut display there are areas with correct colors and areas with wrong colors -> Please look at the attached screenshot. These areas are flickering when scrolling.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? N/A 

Did this work before? Yes Chrome 58

Does this work in other browsers? Yes

Chrome version: 61.0.3163.100  Channel: stable
OS Version: 10.0
Flash Version: 

Disabling flag "color correct rendering" helps. But this should not be a long time solution.

Please attach your color profile to this bug report.

And try Chrome Canary to see if this is one of the issues we have fixed recently. You can install Canary alongside regular Chrome without interfering with profiles etc.

Almost certainly a dupe of  issue 768724 . Sorry, that bug was a stupid mistake on my part. It is fixed in Chrome 62.
The NextAction date has arrived: 2017-10-23
You can now force an upgrade to 62 by going to chrome://chrome
Sorry, but version 62 still showing this bug.
Did you remove flag "color correct rendering" - I can't find it anymore.

There are still areas looking "right" and areas that seem reduced in color. When I move mouse over links, these areas flicker.
Pic attached.

Are you completely sure that you've upgraded to Chrome 62? That screenshot looks exactly like  issue 768724 , which was fixed in Chrome 62.

I just tried both of those profiles, and I've attached the results. They don't exhibit the banding from your screenshots.

Yes, it's sure 62.

I'm using two screens. The error appears, when I move chrome from one screen to the other. After that, banding appears.
The screens are of different types, one is a wide gamut screen, the other a standard one.

Thanks! I managed to reproduce this with 2 monitors and your particular 2 profiles. Attaching 2 videos.

The "move-window" video shows your problem -- when the content moves from one window to another, we see completely incorrect rendering.

The "resize-window" video shows a temporary workaround that you can use until we get a fix landed. If you force the window to re-draw by resizing it horizontally, then the incorrect rendering goes away.

This will likely be fixed in Chrome 64.

Oddly this seems to be particular to the 2 profiles attached -- I haven't managed to reproduce issue with any other profiles.
 Issue 785714  has been merged into this issue.
I think that this was fixed in the process of fixing  issue 766736  -- need to verify.
