Want to know that this confirmation is chrome's bug, and then split it, right?

I'm calling an online product, and the bug is currently running an emergency line. Do I need to get a new bug page again?

Do I need to provide a test address?

I think that this bug is related to bug that I reported: https://bugs.chromium.org/p/chromium/issues/detail?id=724864

I am able to reproduce it using Intel Graphics 530 and problem disappers when switch to Nvidia (change options for chrome in NVIDIA Control Panel).

In my bug report I attached very simple test.

yes I looked at my bug and yours should be one

 Issue 724864  has been merged into this issue.

As per comment#14, this issue specific to Intel Graphics 530.

As inhouse-team doesn't have Intel graphics 530 ,could someone from MTV Team to please look into this issue.

Thanks!

I was good before upgrading chrome58，
There are also many people, this situation should be a universal phenomenon

Can folks affected by this bug please post the contents of the chrome://gpu page pasted into a text file, please? We're trying to determine if this is an issue caused by Chrome or by an Intel/Nvidia driver update or a Windows update. Also it would be great if you could test an older version of Chromium: https://www.googleapis.com/download/storage/v1/b/chromium-browser-snapshots/o/Win%2F444943%2Fchrome-win32.zip?generation=1484879768408272&alt=media and see if the bug reproduces?

chrome 57 version is good，only 58 verison is error

I can reproduce bug on chrome 57 with example canvasArtifactsBug.html. I can't check http://3gimg.qq.com/jiejingweb/TPanoVideo/chrome/chrome-canvas-bug.html because it is not working at the moment.

junov: sounds like this is a regression in m58, could you investigate?

hi, 

I have the same bug on the "waves" of this website (multiple html5 canvas) :

http://bit.ly/2lrcWiV

the effect was ok in chrome 57 ; bug in chrome 58.

I am unable to investigate this because I don't have access to any hardware that reproduces the problem.  I need at least a narrow bisect as a starting point. 

From the screenshots it looks like the textures are getting mismatched
Since this is windows-only, could be a bug in ANGLE.

 Issue 724435  has been merged into this issue.

I've updated to chrome 59.0.3071.115 and the problem persists. Also I don't think it's a windows-only problem. I've a report from an user using OSX.

This bug is getting really annoying as we have received a lots of complains.

Useful info from duplicate  bug 724435  : problem goes away when you disable the display-list-2d-canvas option on the chrome://flags page.

If we continue to be unable repro/investigate this bug in house, we may simply change the "display-list-2d-canvas" option to make it disabled by default.  All of you who are experiencing this issue: can you confirm that disabling this option makes the bug go away?

Yes, disabling display-list-2d-canvas solve the problem.

Yes, I also confirm.

Yes, disabling display-list-2d-canvas solve the problem. bug, It's impossible for users to do this change themselves, or have to solve the problem at the root

> It's impossible for users to do this change themselves

Agreed. We may take care of the issue by disabling the option by default in an update of Chrome. I just wanted to know whether this flag solved the issue for everyone.

good，expect problems to be solved in the new release

ok thanks What version will be released for this change?

@#40 Currently, the fix is in the Chromium trunk, which means Chrome 61.
You can verify the fix by installing the Chrome Canary (nightly build).  This takes only a few minutes and does not require uninstalling your regular Chrome.  Get it here: https://www.google.com/chrome/browser/canary.html

Since this bug harshly impacts several production web sites, I am requesting permission to merge the fix to the Chrome 60 branch so we can get it out sooner.

This bug requires manual review: We are only 13 days from stable.
Please contact the milestone owner if you have questions.
Owners: amineer@(Android), cmasso@(iOS), josafat@(ChromeOS), bustamante@(Desktop)

For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

To milestone owners: The fix has very low risk. It is a one line code change that disables a code path that regressed recently in favor of always using a mature and stable code path that has been in production for years.

If this fix has been tested in Canary and is considered a safe merge (as confirmed in comment 41 and 43), approving merge to M60. Branch: 3112.
