[Ubuntu-x-swat] [Bug 1850874] Re: gnome-shell 100% CPU usage on all cores when animated gif is displayed
I'm not sure what changed to make 19.10 heavier than 19.04, but I can explain what you are seeing. What you are seeing is an OpenGL-based application (Firefox or Chromium) that is being forced to update its entire window constantly. Since it is OpenGL-based, gnome-shell does not have the opportunity to identify just the small area of the screen that is changing, but has to update the entire application window at full frame rate. To do that in software without a GPU is expected to use a lot of CPU and multiple threads, sorry. ** Summary changed: - gnome-shell 100% CPU usage on all cores when animated gif is displayed + gnome-shell (via Mesa/LLVMpipe in a virtual machine) uses all CPU cores just to update the screen ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => Low ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Triaged ** Also affects: mesa (Ubuntu) Importance: Undecided Status: New ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: mesa (Ubuntu) Importance: Undecided => Low ** Changed in: mesa (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1850874 Title: gnome-shell (via Mesa/LLVMpipe in a virtual machine) uses all CPU cores just to update the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1850874/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I can confirm the bug, exact same behavior here. Upgraded from ubuntu 19.04 and same flickering effect. * I open the Tweak tool window * I try to hover one of the left menu's items -> it flickers, I can not manage to click on a menu item sucessfully * If I resize the window (I have to make it larger so that the menu displays larger), then the menu works as expected and the flickering effect disappears - I have to do it everytime I launch the app, though. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1850103 Title: gnome-tweak-tool window keeps flickering on cursor hovering [Intel Penryn: Core 2 T6600] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-tweaks/+bug/1850103/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Well, the same problem happens in the "Parameters" dashboard. If I get it well, there are three breakpoints: * no left-menu displayed * a narrow left-menu displayed * a larger left-menu displayed In the case of a narrow left menu, flicker happens at least in the Tweak tool and Parameters app. See attached screenshot (flickering happens at a much higher framerate than the gif displays it, as if width were computed in a loop) ** Attachment added: "Peek 31-10-2019 14-01.gif" https://bugs.launchpad.net/ubuntu/+source/gnome-tweaks/+bug/1850103/+attachment/5301770/+files/Peek%2031-10-2019%2014-01.gif -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1850103 Title: gnome-tweak-tool window keeps flickering on cursor hovering [Intel Penryn: Core 2 T6600] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-tweaks/+bug/1850103/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
