Videos hang / freeze for a few seconds on Ubuntu 18.04

Solution 1:

disabling hardware acceleration in chrome helped me, installing new kernel didn't

Solution 2:

to resolve the issue, simply install kernel 4.3.0 and everything works as expected!

copy/paste the following to terminal:

cd /tmp/
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-headers-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-headers-4.3.0-040300_4.3.0-040300.201511020949_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-image-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
sudo dpkg -i *.deb

Run these commands and reboot, selecting kernel 4.3 in grub extended settings.

hope this helps, as it did for me.

best regards
