Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36 Steps to reproduce the problem: 1. Go to an established canvas website (e.g. http://html5games.com/) 2. Notice how slow the apps are 3. Install version 59.0.3071.86 and notice no problem What is the expected behavior? No delays. What went wrong? Performance monitor on the app I am building shows Composite Layer delays in the 400-600ms range that didn't exist before. Did this work before? Yes 59.0.3071.86 (confirmed working but it could work in a later version) Does this work in other browsers? Yes Chrome version: 61.0.3163.100 Channel: stable OS Version: 10.0 Flash Version: I noticed this with the latest Chrome update. I went to another website to confirm the performance issue. I then uninstalled the current browser and installed 59.0.3071.86. No problem. Then the browser updated itself and the problem is back.

The above screen shot is scrolling in google maps. Compositing delays are all over 500ms. This one is taking an animation script from this issue: https://bugs.chromium.org/p/chromium/issues/detail?id=770310 The result is 5 fps. I'm not technical enough to identify the issue further, except that I can tell you all those green compositing bars should not exist. My gut tells me that this is an underlying bug for a number of issues being posted.

Tested a little further. It is some sort of resource issue. My computer works fine with only one monitor running. The problem screen shots are with 3 monitors. Also, to confirm, this is/was not an issue with version 60.0.3112.

Unable to reproduce the issue on Win-10 using chrome reported version #61.0.3163.100 and latest canary #63.0.3233.0. Attached a screen cast for reference. Following are the steps followed to reproduce the issue. ------------ 1. Navigated to URL: http://html5games.com/ and opened performance tab in dev tools. 2. Did not observe any lags or green compositing bars. dldubois@ - Could you please check the screen cast and please let us know if anything missed from our side and also please check the issue on latest canary #63.0.3233.0 by creating a new profile without any apps and extensions and please let us know if the issue still persist or not. Thanks...!!

Try this: In Chrome 61, navigate to chrome://flags, disable "color correct rendering", and hit the "Relaunch Now" button. Does that make the problem go away?

A few things. First, I should have been more clear. You need to run a game that utilizes an HTML canvas element within the HTML5games site. The problem I am reporting is strictly with the canvas element rendering. Second, I checked this in Canary (63.0.3234.0) and the problem is gone. Lastly, I went back to Chrome 61.0.3163.100 and disabled the "color correct rendering." This also fixed the problem in the current version. Thanks for the help.

Disabling "color correct rendering" also resolves the issue I was seeing in 61.0.3163.100 ( Issue 770580 ) on google maps, sheets, etc.
