[Bug 1772365] Re: gnome-shell + chrome doing nothing consumes high CPU all the time
I think what reported by Lorens may be totally unrelated to the use of Chrome. The use of VirtualBox, latest version 5.2.18, with a Ubuntu 18.04 64bit guest with 3D acceleration **enabled** and maximum VRAM configured (128MB) is completely unusable because of extremely high memory usage of gnome-shell, independently of the application launched: you can launch nothing or launch firefox, for example, and the session will become unusable pretty soon. It may be worth some more investigation of VirtualBox+3D acceleration use case. My host is actually Windows 10 64bit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772365 Title: gnome-shell + chrome doing nothing consumes high CPU all the time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1772365/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Lorens, You may be experiencing multiple bugs. We would like each bug report to be about a single issue, but here's a list of some of the major issues we hope to fix soon: https://trello.com/c/pe5mRmx7 The list is likely to grow a little too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772365 Title: gnome-shell + chrome doing nothing consumes high CPU all the time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1772365/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1772365] Re: gnome-shell + chrome doing nothing consumes high CPU all the time
I am not quite sure I have *this* bug, because it continues after I close Chrome. I am using Bionic Beaver in a VirtualBox with 4 CPU threads and 4096 (later 6144) MB RAM out of my 2015 MacBook Pro's 8 CPU threads and 16 GB RAM. When I start up, everything seems fine. With one single Terminal open running top, without touching the keyboard or mouse, the gnome- shell runs at some 1 to 4%, which I find extreme, but the system is perfectly useable. The slightest use (unlocking the screen after lock, moving the terminal window, of just hitting space repeatedly to make top refresh), makes the CPU usage of gnome-shell shoot well over 50%, up to 95%. When hitting space, top and xorg never go above 6% each. Using Chrome in itself does not cause any problems for me. However, after opening a video full-screen, the system slows down to a point where it is not useable, and this state continues after closing Chrome. The mouse pointer itself moves without difficulty, but the highlighting of elements under the mouse and the change of shape of the mouse pointer takes up to twenty seconds. For example, opening a new terminal by right-clicking on the left icon and choosing New Terminal needs several (~ tens of) seconds for each click and mouse highlight to be echoed by the screen, while gnome-shell usage is in the 70s. Before doing a fresh reinstall with 18.04, this same hardware was running 16.04, with no problems worth mentioning (when opening 20 heavy tabs at once by telling Chrome to open all the tabs in a folder, I could usually start reading one of the lighter ones after only a second or two, scrolling through it while the others loaded). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772365 Title: gnome-shell + chrome doing nothing consumes high CPU all the time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1772365/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1772365] Re: gnome-shell + chrome doing nothing consumes high CPU all the time
All, Can you please test to see if moving the Chrome window away from the launcher (on the left) reduces the CPU usage of gnome-shell? I know that having windows changing near the launcher is a problem. And I will get back to fixing that soon (bug 1743976). ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772365 Title: gnome-shell + chrome doing nothing consumes high CPU all the time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1772365/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
