Fullscreen youtube videos lagging a lot

Question

In my PC, I can watch youtube videos without any problem. However, they lag so much on fullscreen, that it's basically impossible to watch them. How can I fix this?

Solution 1

You should check your about:gpu section in Chrome/ium. In older PC's HW Acceleration is disabled by default and you only can enable it by overriding the settings in the about:flags.

• Open the about:flags in your address bar
• Look for Override software redendering list
• Click "Enable"
• Restart Chrome/ium

Solution 2

Had the same problem.

Then I realised Chrome already Flash player built in.

I had also installed the Flash player manually so they were apparently interfering with each other. I just disabled the built in Flash in Chrome and voilla. No lag anymore in full screen.

Hope it helps someone.

Solution 3

I have solved using youtube HTML5 video player.

You can enable HTML5 video player using the following page: http://www.youtube.com/html5

Now videos are fast and the laf was gone. I have tested it on Chrome.

Solution 4

This happens to me as well, specially on my older PC, if I watch a youtube video in fullscreen, it lags. What I usually do is to stretch the screen, but not to fullsize or I play it on VLC Player, where it does not lag anymore in full-screen.

To play a Youtube video on VLC Player, copy the address (if you are using secure "https" connection, remove the "s", make sure the link is http://www.youtube.com/watch). Then go to File -> Open Network Stream and paste in the main YouTube URL for a video.

Unfortunatelly this only works with youtube videos for me, Vimeo videos don't play on VLC.

Is your internet speed ok? Also, have you tried turning down the player's resolution?

This is not a solution but a workaround

I disagree with Joren -- the questioner asked about YouTube, not Flash. Google has been moving more and more of their videos to be HTML5-player compatible. Also Adobe has dropped linux support for their Flash player, so it has only received security patches for several years now.

Was your lag in fullscreen mode only?

did you try xserver-xorg-video-amdgpu?

@Sergei I don't remember. I left Ubuntu for Arch and am now running lag-less.
