I am experiencing color glitches and artifacts on youtube. Tested with other browsers, everything is normal.
Chrome Canary - 61.0.3149.0 (64 bit)

The glitches don't show if I pause the video so I recorded my screen.

Updated to 61.0.3149.0 this morning and I am experiencing weird tearing of blues and reds in all videos now both normal sized and fullscreen. I have even verified if I pause during the tearing, the torn colors will "catch" up really fast to the normal frame, even if paused. Reminds me of what old 3d movies used to look like.

I couldn't repro this bug on my Win7+Chrome 61.0.3153.0 (canary). 
I am using NVidia Quadro display card, played multiple random YouTube video.

what is your display card?

jbauman@, has anything changed recently in who we present videos? swap chains, etc.
There shouldn't be any differences in the last week or so, but before that there are two possible changes - one is that we can use overlays, another involves delaying the copying of video in some circumstances. We should get about:gpu from the affected users to see what's happening on their systems.

Delaying the copying sounds highly suspicious.
This is most likely a dupe of https://bugs.chromium.org/p/chromium/issues/detail?id=738078 (which has about:gpu in it)

Based on that about:gpu, delayed copy should be disabled because it's an NVIDIA GPU (which had other types of color-related issues).
 It would be good if we could get a bisect as well.

Expanding this bug to Android as well.

I experienced it while watching embedded youtube video

jain..@ on the android repro, would you be willing to use chrome://media-internals to send the info for the media player?

i'd like to see if it's hw or sw decode that's affected.

Can people who reported this still reproduce the bug? I suspect this was caused by r482759 and fixed by r487980.

+ ranjitkan@ or pbommana@ to try to repro (ptal comment #12)
Rechecked this issue on Windows 10 using chrome version 61.0.3163.39 and Canary version 62.0.3185.0. Unable to reproduce it on Youtube.com. Played the video on both normal and full screen mode.

Graphic driver was NVIDIA Quadro k600

Thanks.!

This was probably a dupe of  issue 738928  which was fixed a while back. I'm closing as WontFix per #15.
