[Desktop-packages] [Bug 2052913] Re: Large Performance Regression in gnome-shell from Ubuntu Jammy to Ubuntu Noble
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 Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2052913 Title: Large Performance Regression in gnome-shell from Ubuntu Jammy to Ubuntu Noble Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: New Bug description: Test system: ARM64 Ubuntu Jammy (gnome-shell 42.9-0ubuntu2) and Ubuntu Noble (gnome-shell 45.3-1ubuntu1) Default Ubuntu GNOME desktop environment used with no user added extensions.

Sorry I missed the replies in my email I will test disabling the extensions later I can confirm that these are the same (because I use the same custom kernel and GL/Vulkan/EGL/GLES driverstack): * lspci -k # to see if the kernel driver changed * es2_info | grep ^GL_ # to see if the GL driver changed I will not be able to do this because of no wayland support in the driverstack: Or by checking the scanout method using MUTTER_DEBUG=kms and grepping the log for "Post" (Wayland only though).

It also sounds like fullscreen direct scanout might have worked in jammy but doesn't in noble. You can test that theory by comparing the windowed performance between jammy and noble.
