I can't really test dns throttling, so the answer is no. Latest experiences on this tricky issue. I had problems with prover management in years time.
WIFI is unusable (using usb tethering), so and it's kept "disconnecting". (disconnecting mean, that it's connected, but the connection dies (locks the chrome tab, even if I'm kept pushing the refresh button - if I open a new tab many times the responsiveness comes back again) unlike xperia phone, where even if the wifi is disconnected at some point not so frequently, the tab does not die, connecting back, right away will get the connection and update the page, if it's necessary) Upgraded mesa on daily basis, and it was getting worse. I have disabled the dimming (power management), and the problem seemed to be disappeared for a while. When I'm opening chrome before packageit process is finishing its job. (so right away after I see the default desktop screen), I'm more likely getting system-ud cpu hog (50-100%), and flickering issues. When I'm restarting with it, system-ud does not appear on the top 30 processes. When I restarted my chrome browser (the initial ubuntu loading has been finished - no CPU usage - 1-2%), the flickering issue has not happened that frequently. I have disabled also screensavers. (i had to install the program to disable it) It seems to happen on full screen only and sometimes I have a feeling that the ubuntu is just stopping after some inactivity period, as my wifi is gone in the background. (unfortunately even if I set wifi always on xperia, it seems disconnecting the wifi, but not that frequently, and when i'm activating the xperia again goes back - but in this case wifi should be always active) I think it's something with the power management, what I felt so buggy in the last couple of years. (the only thing which has been resolved, that from hibernate mode it's not corrupting my ubuntu anymore, and doesn't make cpu hog also) It's very hard to really figure out when the problem happens, but I do think it's nothing to do with mesa, it's something else, which keep killing the mesa. The voice was steadily working, just every 5-10 sec video playback stopped for 3 sec. It's the worst case scenario. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1803848 Title: Playing video on chrome freezes frequently (Too slow to catch up) Status in chromium-browser package in Ubuntu: Confirmed Bug description: Latest update of ubuntu made some strange problems: system-udev made a high CPU usage on nvidia, i have made a restart on the udev, thus i have decided to bleach it and run the following commands: sudo systemctl start systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket sudo systemctl stop systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket It solved some of the flickering problem, but it did not disappear. 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
