The last two releases of Chrome for my Ubuntu 16.10 have had slow video playback in Chrome only on the external monitor only when fullscreen and only when that chrome window/tab is NOT focused (i.e. if I click another window on the laptop monitor the video plays fine full screen on the external monitor).

When the video is jerky I notice the Xorg process uses 100% CPU. When I click on another window on the other monitor the video plays fine and the XOrg CPU drops right off.

Not the end of the world but annoying having to always move the mouse off the screen and click a random window on the laptop monitor when trying to watch a movie!

I ran Intel Graphics Tool Update and have ensured I am running the latest Chrome v60.0.3112.90 (Official Build) (64-bit)

I have tried the answer here: Chrome running slow in fullscreen mode (not Flash related) to no avail.

Any advice much appreciated.

  • Chrome dropped pepperflash in favor of html5 starting with ver 59. I rolled back to ver 56 because of video playback issues associated with this switch

  • Thanks for the info. I tried to install pepperflash manually and now chrome://flash displays: Google Chrome 60.0.3112.90 () OS Linux Flash plugin /home/<home>/.config/google-chrome/PepperFlash/ but fullscreen playback just on the external monitor and just when the window IS focused is as jittery as before. Is my only option to revert to v56? Thanks!

  • no I don't, I just know on mine the change to ver59 caused video issues, especially when more than one was playing. reverting to 56 fixed it. you may have a different issue

  • Ok thanks I've been playing around with different settings and versions of flash but not been able to fix it (I think I've made the video performance worse). So it really seems the only way is to downgrade :(

This is due to Chrome v59+ removing flash from Chrome.

After lots of trial and error the easiest way I found was to install Google Chrome Beta to use for flash and use Chrome stable for everything else.

I downloaded and installed this .deb file: http://sagasl.uccuyosl.edu.ar/mirror/dl.google.com/linux/chrome/deb/pool/main/g/google-chrome-beta/google-chrome-beta_58.0.3029.81-1_amd64.deb

Then launch via


Then go to chrome://flags/

And disable

Prefer HTML over Flash Mac, Windows, Linux, Chrome OS 
Prefer HTML content by hiding Flash from the list of plug-ins.
# prefer-html-over-flash

Then relaunch.

And now videos should play full speed full screen without jittering using good(!) old flash.
