@karlo: Could you please look into the issue, pardon me if it has nothing to do with your changes and if possible please assign it to concern owner.
Adding RB Label as this is a recent regression. Please remove if not required.

Thank You.

Correction : 
Above issue is not seen on Linux (14.04) LTS machine.

karlo@ Since M-59 is about to move beta channel this issue is marked as RB-Stable, could you please let us know is there any latest update available on this issue?

Just to update the latest behavior, this issue is observed on chrome latest beta #59.0.3071.36. 

karlo@ Could you please let us know is there any latest update available on this issue?

This issue is actually shared with MS Edge.

I am working on issue #716174 at the moment, but coincidentally, the fix for that appears to resolve this issue as well.

Marking as Untriaged as the component it was set to was incorrect.

Reminder that M59 Stable is launch is coming soon (less than 2 weeks)! Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch ASAP so it gets enough baking time in Beta (before Stable promotion). Thank you!

The site seems to have changed the volume slider to be horizontal and no rendering artifact is present (maybe they knew about this).

Could someone else please confirm that they see what I am now seeing?

The issue appears at some window sizes (that determine the video size). The original link redirects for some reason. This works: http://www.firstpost.com/world/watch-traditional-gold-mining-in-nicaragua-3477496.html

Given that it only happens sometimes, and a resize easily fixes it, we'll punt until next release.

avshaikh@: Could you please confirm this from your end as well, if this is still an issue?

C#0 link doesn't work anymore and link in C#11 doesn't show any such behavior on the latest canary(61.0.3114.0) on Windows-10 at my end.

With response to comment #12,

Retested above issue in latest canary (61.0.3116.0) on Win-10 machine and issue is still reproducible. C#0 link doesn't work anymore but issue can be reproduced using link given in C#11 ( http://www.firstpost.com/world/watch-traditional-gold-mining-in-nicaragua-3477496.html ).

Note : Now issue is only reproducible while video is being played in fullscreen mode. Kindly navigate to link given c#11 , play video in fullscreen mode (wait until adv. finishes) and hover mouse on 'volume' icon, observe.

Thank you!

We are approaching M60 stable release, so it would be really great if we'll land a fix ASAP.

Thank you!

Punting to M61 as we're a week away from M60 stable and only taking high priority fixes.  Per #11 this isn't particularly severe, and it's been around since M58

Retested above issue in latest Chrome canary #62.0.3165.0 on Windows(7,8) OS and issue is still reproducible when video is played in fullscreen mode.
Test URL : http://www.firstpost.com/world/watch-traditional-gold-mining-in-nicaragua-3477496.html
Note : On Mac(10.12.3), no need to play video in full screen mode, issue can be seen even when video is running in normal mode.

Thank you!

This shouldn't be a release block stable, Since the bug been there for couple of stable milestones and as per offline chat with eae@ this is more of site implementation bug then a Chrome bug. hence removing blocker label.

No longer reproduces.
