this might be 64-bit linux specific.  I use gentoo.

Also, I have broadband internet from charter spectrum in washington.  firefox works just fine.
 

Comment 1 by mrjri...@gmail.com, Feb 24 2018

Chrome has been corrupting my 64bit debian linux Toshiba Satellite laptop continually for the last year.  The hardware acceleration has been the culprit.  Very frustrating and after years of using Chrome, I'm actually considering leaving it for another non-chromium based browser.

Every time this happens, I get dumped into some crunky command line interface on bootup.  And the only reason I'm even able to recover the machine is because I have some software background.  I imagine most people have to give up and re-install the OS.

Hardware acceleration is a very delicate issue and you *have* to get it right or you can totally toast people's machines.

Unable to reproduce this issue on reported version 64.0.3282.167 using Ubuntu 14.04 and  Ubuntu 17.10. Attaching GPU of machine checked.

1. Played Youtube video continuously for 15 mins and didn't observe any video stuck and didn't observe any buffering of video.

@Reporter: Please check the issue by resetting all flags to default from chorme://flags, check the issue on new profile which do not have any apps/extensions. If possible please try on another system connected to same network and report us back with the behavior. This would help in further triaging of the issue.

Thanks!

Did the reset of all flags, and removed all extensions except for two I wrote myself that do nothing but mess with bookmarks and tab order.

Comment 6 by shent...@gmail.com, Mar 1 2018

Oh right, it started working for awhile but after a few cycles on youtube it's back to its "phantom buffering" routine.
Labels: -Needs-Bisect
Re-checked the issue on Ubuntu 14.04 and Ubuntu 17.10 with steps mentioned above and is not reproducible from TE end.

As per comment#6, issue seems to be inconsistent from reporter end. Hence removing Needs-Bisect label.

Could someone from Internals>Media team please have a look at this issue.

Thanks!
I've been occasionally experiencing what I assume is this issue (YouTube video getting stuck with the loading animation, neither pause and play nor skipping around will get it unstuck, page reload is necessary) when trying to replay the video after it's finished by clicking the replay button or clicking a timecode in the comments. The problem is intermittent for me too, it doesn't happen on every video. I also am on Linux (Lubuntu 17.10) and am using the latest dev channel Chrome. I've observed this issue over several dev releases of Chrome in both the new and old YouTube layout and while I can't say for certain that this didn't happen before, I've never noticed it until a few weeks ago or so.
are you using wifi or wired network? is your network speed good enough?

Comment 10 by shent...@gmail.com, Apr 10 2018

I'm on home broadband, going through a wifi router's wired port, and from that to the cable modem and from there via coax to Charter.  Dunno what's upstream of that but I'm on their Spectrum service.
Status: WontFix (was: Unconfirmed)
firstly I couldn't repro this bug on Ubuntu Linux desktop device.
secondly, please try these steps to see if this bug repro:
1. create new profile, navigate to repro YouTube video on the new profile.
OR
2. play video in incognito mode
OR
3. check if you see the network buffering issue in playing other YouTube video. if only on this one, it is possible video problem so please Report Issue to YouTube.
