Paco, with this last comment do you mean that after solving this DNS throttling issue the problem with video playback is seemingly resolved?

I'm running on 120Hz, sometimes the screen resolution has been changed so quickly on boot, that i have noticed lines at the bottom of my screen. (like in a bad monitor) Why ubuntu needs to change that so frequently, it just amortize the graphics card. The real issue is that my video playback youtube / scolling main site of origo.hu (local news portal) etc. flickering frequently. It is too slow to catch up. Suddenly stops, and after 2-3 seconds it restarts. It only happens on chrome seems to me, and does not happen when i disabling gpu. https://bugs.chromium.org/p/chromium/issues/detail?id=906861#c8 As a matter of fact, my CPU usage is not that much with or without gpu, so on gnome-shell some optimization needs to happen. Why i have GPU acceleration, if the gnome-shell swallows the benefit? On firefeox it does not happen, but the WebConsole CPU usage is 3 times more than in chrome. (70-80% on a full hd video, which is burning up all my cpu time, so it cannot be the solution to jump to firefox) Other thing is that the cooler less frequently making noise without gpu, even if the CPU has got higher load. If the cooler is running on high frequency, i hardly able to work. The non-accelerated Chrome CPU usage is half of the accelerated firefox cpu usage. I have posted the problem on both side, because i have a feeling there is problem at the middle, how ubuntu and chrome corporates with each other. Visual studio code also has some high CPU problem while scrolling, cooler makes noise. To me seems that it does matter whether the gpu makes the heat or the cpu regarding to cooling insensitivity. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2017-08-07 (471 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) Package: gnome-shell 3.28.3-0ubuntu0.18.04.3 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-39.42-generic 4.15.18 Tags: bionic third-party-packages Uname: Linux 4.15.0-39-generic x86_64 UpgradeStatus: Upgraded to bionic on 2018-08-24 (89 days ago) UserGroups: adm cdrom dip docker lpadmin plugdev sambashare sudo vboxusers video wireshark _MarkForUpload: True --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2017-08-07 (471 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) Package: gnome-shell 3.28.3-0ubuntu0.18.04.3 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-39.42-generic 4.15.18 Tags: bionic third-party-packages Uname: Linux 4.15.0-39-generic x86_64 UpgradeStatus: Upgraded to bionic on 2018-08-24 (89 days ago) UserGroups: adm cdrom dip docker lpadmin plugdev sambashare sudo vboxusers video wireshark _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1803848/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
