It appears the high CPU of gnome-shell with totem on Wayland at least is
due to the totem app window redrawing at 60Hz seemingly only on Wayland
(bug 1698282). When this happens, the compositor will have to upload
(copy) the window texture from CPU to GPU 60 times per second, which is
CPU-intensive. This would happen with any software ("shm") surface that
is large and redrawing frequently. So I guess that might include Firefox
too.-- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1696305 Title: High CPU usage in gnome-shell just redrawing the screen (Firefox is running) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1696305/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
