I tested all of these: * gnome-extensions disable tiling-assist...@ubuntu.com * gnome-extensions disable ubuntu-appindicat...@ubuntu.com * gnome-extensions disable d...@rastersoft.com * gnome-extensions disable ubuntu-d...@ubuntu.com
and then had no effect on the performance on noble (yes they did disable and I could see the visible changed in UI). I tried rebooting afterwards with no improvement. I did this: You can test that theory by comparing the windowed performance between jammy and noble. noble performance is about equal with a maximized window and fullscreen (140fps) jammy performance is a bit lower maximized window than fullscreen (162fps vs 177fps) but I see gnome-shell cpu usage at ~50% when when maximized window (vs 0-1% in fullscreen) so yeah definitely appears to be an issue with fullscreen direct scanout not working and additionally just gnome performance regresssions with windowed mode . -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2052913 Title: Large Performance Regression in gnome-shell from Ubuntu Jammy to Ubuntu Noble To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2052913/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
