Issue descriptionUserAgent: Mozilla/5.0 (X11; CrOS armv7l 10323.67.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.209 Safari/537.36 Platform: 10323.67.0 (Official Build) stable-channel nyan_big Example URL: https://bugs.chromium.org/p/chromium/issues/detail?id=836467 Steps to reproduce the problem: 1. View a video embedded in a webpage (e.g. at issue 836467 ) 2. Notice that the video is blocky/pixelated What is the expected behavior? Videos should be displayed properly. What went wrong? Some videos are extremely blocky/pixelated, to the point of being unwatchable. Does it occur on multiple sites: N/A Is it a problem with a plugin? N/A Did this work before? N/A Does this work in other browsers? N/A Chrome version: 65.0.3325.209 Channel: stable OS Version: 10323.67.0 Flash Version: 29.0.0.113 This doesn't seem to happen on YouTube (but I think it has in the past -- maybe it happens on some videos but not others?)

Agree. The encoded resolution of that video is 1920 x 1200, and down scaling reduces to be roughly 1/4 that size. anowlcalledjash@ - does the video look crisp if you show it in fullscreen mode? QA folks - Please let us know if you have a repro.

No repro. @anowlcalledjosh@gmail.com - Please respond to comment #2. Can you repro with current Chrome browser?

Sorry, I've not been using my Chromebook much recently – I'll try to reproduce it over the weekend, but videos seem to be working fine so far (67.0.3396.87).

#2: I do remember the problem persisting even in fullscreen mode.

Please can this be reopened? It's not fixed – I've now managed to reproduce on 71.0.3578.94 (platform 11151.59.0).

Thanks for reporting, anowlcalledjosh@. Is this regression? Reading the comments, this is fixed in M67, but happen again from M71? What about M70? What if HW video decoder is disabled by chrome://flags/#disable-accelerated-video-decode? Thanks in advance.

If that flag is disabled, videos play fine. I have no idea about M70, sorry - I mostly stopped using my Chromebook by comment #5, so I don't know if it was ever fixed.

I have no idea about M70, sorry What version did you experiment? Still M65? Could you try to uprev M70 or perhaps M71?

I cannot reproduce this on M71. How likely do you see this problem?
