Public bug reported: The problem exists for months and I didn't find a good answer on it. It affects many softwares: Cheese, Super Tux Cart, VLC (when I rewind the video the sounds continues, but the video stops), youtube, Hangouts and every software where video is played.
I experienced that there are 2 things that can break it: - if I move the mouse out and in on the affected window (it doesn't work in full screen) - if I open the system monitor, the problem also disappears other people also face with this problem: https://unix.stackexchange.com/questions/447696/ubuntu-16-04-18-04-video-playback-lags-stutters https://askubuntu.com/questions/1032035/ubuntu-18-04-budgie-desktop-video-lag-youtube-twitch-in-chrome https://askubuntu.com/questions/1030074/my-video-player-in-ubuntu-18-04-lts-lags/1030194 https://askubuntu.com/questions/1030155/youtube-video-lag-on-18-04 Ubuntu 4.15.0-23.25-generic 4.15.18 it was upgraded from 16.04 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: cheese 3.28.0-1ubuntu1 ProcVersionSignature: Ubuntu 4.15.0-23.25-generic 4.15.18 Uname: Linux 4.15.0-23-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sat Jun 16 14:34:26 2018 ExecutablePath: /usr/bin/cheese InstallationDate: Installed on 2016-08-04 (680 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: Dell Inc.
