Issue descriptionUserAgent: Mozilla/5.0 (X11; CrOS aarch64 10176.65.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.134 Safari/537.36 Platform: 10176.65.0 (Official Build) beta-channel bob Example URL: https://www.youtube.com/watch?v=Fa1bj14j4_8 Steps to reproduce the problem: 1. Open a youtube video, preferably with >=1440p quality 2. Set video quality double of viewport e.g. 1440p video on 720p viewport, 720p video on 360p viewport etc. This info is available in "Stats for Nerds" 3. Wait until the UI overlay (play button, progress bar, etc) disappears. Make sure there are no overlays, windows, cursor on top of the video viewport. Some channels have small icon overlayed on each of their video, on the bottom right side. You need to find a video without one to reproduce. What is the expected behavior? The video plays smoothly What went wrong? Lower half of the screen goes black, and the rest flashes rapidly. This video shows shows what it looks like: https://www.youtube.com/watch?v=DsZXZLKH8F4 Did this work before? No Is it a problem with Flash or HTML5? N/A Does this work in other browsers?

They are both manufactured in 2017-10, according to the sticker on the bottomplate. You can see more infos about the problem in this link. This is where I first troubleshooted: https://productforums.google.com/forum/#!topic/chromebook-central/szSU1ayYQXM;context-place=forum/chromebook-central There are a few other posts reporting the same bug: https://www.youtube.com/watch?v=DsZXZLKH8F4 (same link as the one I posted on "What went wrong?") https://www.reddit.com/r/chromeos/comments/7ss0zo/chromebook_flickering_on_youtube_anyone_having/ https://productforums.google.com/forum/#!msg/chromebook-central/ineTdFDardE/MsFUVZTWEAAJ

Hi, thanks for the information, that is very helpful. the factory also reported the same issue to us recently, but they said it's hard to reproduce. i followed the links, and found Park Sung-Yong's comment at: https://productforums.google.com/forum/#!topic/chromebook-central/szSU1ayYQXM;context-place=forum/chromebook-central "Park Sung-Yong said: I could confirm that it is not an issue of youtube. https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_video Since the source video is 320x176, I set the width as 160. The glitch appears when the video plays" that seems matched the test steps described at #1 right? (half resolution video, no overlay, hardware video decode) i'll ask the factory to try that to see if we can reproduce this issue easier :)

Hello, I am very happy that I've finally got a chance to get it fixed by the right people :) I am the original poster of your link, Park Sung-Yong, and it is the exact same issue as I posted here. Ask anything you'd like to know, and I'll gladly answer them. Additionally, I have collected production date from a few people. One person with one glitchy product reported it was manufactured in 2017-09 (https://www.youtube.com/watch?v=DsZXZLKH8F4). I had two products with the issue, and they were both marked as 2017-10, but one person said they had one from 2017-10 without the problem (https://productforums.google.com/d/msg/chromebook-central/szSU1ayYQXM/licFm_G0AwAJ).

Hi Park Sung-Yong, thanks, i think this issue might related to the display module or gpu... if it's possible, could you help to try: 1/ switch to developer mode 2/ enter VT2(or crosh terminal) 3/ run these commands: localhost # echo '!--enable-hardware-overlays' > /tmp/args localhost # mount -B /tmp/args /etc/chrome_dev.conf localhost # restart ui 4/ confirm /etc/chrome_dev.conf has "!--enable-hardware-overlays" at the end of file, then retest this issue this is to disable our hardware overlays. i'll open a partner issue to discuss this issue with some googlers and asus team, and update new progress here :) since the chinese new year is coming, we might be out of office for about 2 weeks. thanks for your great help again :)

I will test it probably in 24 hours and tell you the result, but before that, I think I need to tell you this first: I might not be able to do another test, because I have to return it back to the seller soon. I bought this chromebook on Amazon, and had it shipped to Korea. Since it is not sold in Korea, it is not likely be covered by Asus Korea -- the operator from the service center said so. So, to comply with the return policy of Amazon, I have to send it back in a few days. I will probably order another one, but it should not arrive soon, and it is not certain if the new one will have the same issue or not.

Hi Park Sung-Yong, it's ok, we can ask the factory to find more problem devices using your test steps:) but that would be after chinese new year too. Hi guys, FYI, the partner issue is: https://partnerissuetracker.corp.google.com/issues/73189739
,
Feb 12 2018
so, i've got a feedback from asus, the test steps can repro about 100% on that device. and disable hardware overlay seems could avoid that
,
Feb 12 2018
Thank you for posting the solution! I haven't tested it yet, but I have a couple of questions 1) Will disabling hardware overlay hinder performance or battery time? 2) What is the likely reason? Hardware defect, device driver error? (because in the latter case, I won't have to deal with another refund and wait until a patch) I will test the flag soon and post how it goes. Happy chinese new year! We, in Korea, also traditionally celebrate it as well :)
,
Feb 12 2018
Hi Park Sung-Yong, 1/ yes, it could affect that, but not much i think 2/ i'm not sure about that yet, but i think we would fix it in software and thanks, happy 춘절 too ;)
,
Feb 13 2018
oh right, I almost forgot posting it It works seamlessly, much better than just disabling hardware decoding. I hope it gets patched soon =)
,
Feb 23 2018
Hi guys, some updates: 1/ this issue could repro on every bob devices 2/ we found the root cause(wrong hardware register config for yuv hardware overlay), and will upload patches soon :)

CL has been committed and we'll try to get it out in the 65 release of ChromeOS.

Marking this as fixed, thanks for the bug report. |
