Title:
  Last LTS version of ubuntu use a deprecated gnome version with crashes
  and known performance issues

Status in gnome-shell package in Ubuntu:
  New

Bug description:
  Sometimes gnome becomes too slow and consumes too much CPU, during the
  day sometimes it runs very smoothly and suddenly it gets extremely
  slow and the cpu consumption gets too high.

  I have notified the Gnome development team of this, providing all
  possible evidence, but they have told me that my system uses an
  outdated and unsupported version of Gnome:
  https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6788

  It is the version that comes by default in the latest updated version
  of Ubuntu 22.04 LTS.

  Why is Ubuntu using an outdated version that has known performance
  issues?, how can I fix the problem I'm currently having with my
  system?

  
  The main problem:

  Enviroment:

  whk@whk-MS-7D53:~$ lsb_release -a
  No LSB modules are available.
  Distributor ID:       Ubuntu
  Description:  Ubuntu 22.04.2 LTS
  Release:      22.04
  Codename:     jammy
  whk@whk-MS-7D53:~$ gnome-shell --version
  GNOME Shell 42.5

  I don't use third party extensions in gnome shell, the problem is observed in 
xorg and in wayland.
  My hardware:

  - CPU: AMD Ryzen 7 5800X3D.
  - RAM: 128 GB 3200Mhz.
  - Disk: WD BLACK 2TB SN770 NVMe.
  - Motherboard: MSI MPG X570S Edge.
  - GPU: XFX Speedster MERC319 AMD Radeon RX 6800 XT.

  Sometimes gnome becomes too slow and consumes too much CPU, during the day 
sometimes it runs very smoothly and suddenly it gets extremely slow and the cpu 
consumption gets too high, the dock barely responds, the windows move very 
slowly, but at the same time I can open a new generation game and run 
excellently at 60fps (need for speed heat over steam), so I doubt it's a 
graphic driver problem.
  I don't know why this happens, it happens randomly during the course of the 
day. I've checked the computer logs but currently I don't see anything relevant.

  Some time ago I raised a similar problem:
  https://gitlab.gnome.org/GNOME/tracker/-/issues/342 , i still have the
  same symptoms but without the log messages in rsyslog.

  I have created a video reproducing this problem: 
https://www.youtube.com/watch?v=aRhgkfbu4AI
  Some points to consider:

  - I don't use gnome shell extensions.
  - Gnome software and Snap store are uninstalled so the consumption issue 
doesn't go that way.
  - All my apps are closed, I don't have any personal apps open in the 
background.
  - The open directory has no files so I rule out that it could be a high load 
due to content rendering.
  - Disk usage is low so there are no IO blocks.
  - The whole gnome environment gets slow, not just the windows, but also the 
context menu display, side dock navigation and top menu display when trying to 
shut down the computer, but the content of the other applications is very fast, 
so I don't think it's a general problem with the equipment or hardware, 
otherwise the other applications would have a very bad performance, but it's 
not like that. I think the problem is caused solely by gnome, but I don't know 
how to diagnose this.

  If you need more information or to run some kind of diagnostic, let me
  know.
