What does that mean? should I specify something in addition? let me know how I can help!

Unable to reproduce the issue on chrome reported version 66.0.3344.0 using windows-10 with steps mentioned below:
1) Launched chrome reported version and turned ON "Use hardware acceleration when available"
2) Played a 60fps video on youtube and opened Devtools -> Rendering and checked the FPS meter
3) Able to see 60 fps when "Use hardware acceleration when available" is ON and OFF

@Reporter:
Please find the attached screen cast for your reference, try to test this issue by creating new person with no apps and extensions in it and let us know if the issue still persists.

Thanks!

Whoa you even made a video! the dedication haha!
I made a new user, free of all extensions, with previous user page closed,
Repeated the same cycle, still finding myself having fps locked to 30fps when a youtube video is on fullscreen.

Maybe chrome canary is having the difficulty to sync with my rig\hardware? 
Could it be the case?

Is the video playing 60fps in a window?

+liberato, sunnyps since this is on canary.

awesomedanx: To be clear, you're saying this does not happen with stable? Just Canary? If so, since we can't reproduce, can you poke around with a few older builds to see when the issue was introduced? Build 535276 corresponds to 66.0.3343.0:

Unfortunately it began with me noticing that 60fps videos arent buttery smooth when fullscreened, this is how I lead myself to enable the fps meter to determine the frame rate of the videos I'm watching, unfortunately its been a problem that kept on going for months, maybe even a year, I never bothered making a case about it because I just hoped that its a common thing and that I might see it in the next builds, so going to previous builds wouldnt really resolve the case.
This only happens when Hardware Acceleration is on.
I think its most likely because the canary might not be optimized with some hardware? I think? if this the case, I think it should be forwarded to the developers so they could work around it as theres might be more people out there that Canary isnt using the potential of their hardware, as part of polishing the great project which called the Canary project! (that is by of course bound to have any sorts of bugs)

Can you try setting Win 8 compatibility mode on Chrome to see if that fixes the issue? There's an OS bug this sounds similar to; issue 775898

I have set my chrome's compatibility with win8 and it seems like it resolves the case!
Thank you!
Would the Canary developers consider optimizing Chrome Canary with windows 10 anywhere in the near or far future?

It's a bug in Windows, so we're waiting on Microsoft to release a fix; per issue 775898 that should be sometime this month.

Oh, awesome!!!
Is there a way to get updated on this whenever the update that resolves the issue comes out?

You should be automatically starred on the other issue since I duped this one in there; so you should get e-mail updates when we receive confirmation from microsoft.

Oh neat! Thank you for your time!!

The new windows 10 update:

Seems to resolves the issue
