i tested with various videos from different sources, the result is the same.

when drawing onto a canvas smaller no bigger than 256x256 the bug doesn't happen. the same for any size when disabling hardware acceleration. this suggests it's a GPU issue.

Unable to reproduce the issue on reported chrome version 63.0.3239.132 and on the latest canary 65.0.3318.0 using windows 10 with the below mentioned steps.
1. Launched Chrome 
2. Pressed F12 and opened Dev tools>Console
3. Run the given code in comment#0 

We are getting an "undefined" error message after running the code. Attaching the screenshot for reference.

@Reporter: Could you please look at the screen shot and let us know if we have missed any steps while reproducing the issue. Any further inputs from your end helps us to triage the issue in a better way.

Thanks!

i don't know why you get that issue.
pasting the same code into the console on an empty page reproduces the issue successfully on my machine. i've also tried using http://www.webtoolkitonline.com/javascript-tester.html and the issue was reproduced there as well.

i found the error in the code. try the following either through the console or the javascript tester page:

var canvas, context, video;
function drawingLoop() {
	window.requestAnimationFrame(drawingLoop);
	context.drawImage(video, 0, 0);
}

canvas = document.createElement('canvas');
document.body.appendChild(canvas);

video = document.createElement('video');
video.addEventListener("loadeddata", function() {
	canvas.width = video.videoWidth;
	canvas.height = video.videoHeight;
	context = canvas.getContext('2d');
	video.play();
	window.requestAnimationFrame(drawingLoop);
});

video.autoplay = false;
video.src = "http://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_1mb.mp4";
video.load();

Tried checking the issue using the code provided in comment#8 on reported chrome version 63.0.3239.132 and on the latest canary 65.0.3322.0 using windows 10. We are seeing an error after code is pasted and hitting enter. Attaching the screen cast of the same. 

@Reporter: Could you please check the screen cast and let us know if we have missed anything. Please let us know if anything needs to be run in background.

honest to god, i don't know why you get that error. i supplied some very basic video-to-canvas code. i don't think it can be simplified any further.

Rechecked the issue with the URL http://www.webtoolkitonline.com/javascript-tester.html provided  in comment#5 and the code given in comment#8 on chrome version 65.0.3239.132 and latest canary 65.0.3323.0 using windows 10. We are able to play the video , as we didn't observe any frame jump while the video is being played, requesting some one from inhouse team to have a look into this for further investigation. Hence adding label TE-NeedsTriageFromHYD. Attaching the screen cast for reference. 

Thanks!
