I'm seeing a lot of lag while attempting to view YouTube or Twitch videos, the sound is fine but the video stops until I move the mouse.

Scrolling a web page in Chrome stable (66.0.3359.139) is laggy when using the touchscreen, two-finger scroll on the touchpad seems fine.

Lenovo G500s - i5-3230M - Intel Ivybridge Mobile graphics - 6gb RAM

Upgraded from 17.10 via software updater, 17.10 had been a clean install with nothing extra installed as this is just an internet browsing laptop.

I found a post suggesting running these commands:

sudo apt install libdvdnav4 libdvdread4 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libdvd-pkg
sudo apt install ubuntu-restricted-extra

These helped in that I just have to move the mouse 1 time to get the video to play whereas before I had to move the mouse every few seconds to have the video play.

display info:

sudo lshw -C display
[sudo] password for ubuntu: 
  *-display

Is there any other info that I can provide?

    Okay here is something strange, if I run system monitor and use chrome I no longer experience the lag. Is it because it is polling the CPU? I opened it to see if there was perhaps a CPU spike that was causing the lag. – Jon Delano May 05 '18 at 16:33

    This is a known upstream issue with both chrome and chromium and is NOT distro specific - https://bugs.chromium.org/p/chromium/issues/detail?id=822549 Workaround is to turn off hardware acceleration within chrome/chromium config or use Firefox. – fossfreedom May 06 '18 at 12:43
  • I didn't have this issue at all in 17.10, I will tho, check out your suggestion. Thank you for your reply. – Jon Delano May 07 '18 at 14:43
  • I reported it for cheese developers, but I commented that it affects many other packages. You can subscribe here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777238 – Zoltán Süle Jun 17 '18 at 22:15
  • @JonDelano I want to thank you for providing the only "solution" to this probably that has actually worked for me -- opening System Monitor. Can't believe it works, but it stops the lag! Glad to see *someone* else with this problem – cemulate Aug 25 '18 at 17:39
  • FYI - 18.10 fixes this bug. No need to run System Monitor any longer – Jon Delano Oct 29 '18 at 11:02
