Extreme lag when switching to workspace overview

[Jamie Border]

I recently updated from Ubuntu 20.04 to 22.04 and am experiencing significantly more lag. The most noticeable one is when entering and leaving the workspace overview. In 20.04 this was very fast (~0.5 seconds?) and now it is taking ~2.8s after pressing Windows key before I can see the workspace overview and click to a different window or search for an application. The same in reverse; ~2.8s after pressing Esc or Windows key before I am returned control inside an application.

I currently have some extensions installed but removed them all and was experiencing the same thing. This still occurs if I have no windows opened.

Thanks for the bug report. Please collect a log of the bug happening by:

1. Open a Terminal and run:

   journalctl -f > recentlog.txt

   Leave it running.

2. Reproduce the bug.

3. Press Ctrl+C in the Terminal window.

4. Attach the resulting text file here.

Please also try:

* Uninstalling the (unsupported) Nvidia 520 driver you are using and instead use the 'Additional Drivers' app to install a supported driver version.

* Deleting (yes deleting) all local extensions:

  cd ~/.local/share/gnome-shell
  rm -rf extensions

  and then log in again.

Hi,
I think this issue was primarily driven by me having extremely low storage left on my SSD. You can probably close this however I've attached the log of my doing this anyways. The speeds have improved a lot but still seems slower than 20.04.
Thanks

You've got lots of errors coming from

/<email address hidden>

Please start by removing that one if not all of them.
