On Ubuntu 23.10 after I install the Nvidia driver v535 I get noticeable latency of about 10-15 seconds after I click on any application, be it Nautilus, Terminal, Firefox. The problem lasts for about one minute. More precise steps:

1. Install Nvidia drivers (using sudo ubuntu-drivers install)
2. Reboot
3. Login to X11 session (which becomes the default when Nvidia drivers are installed)
4. Quickly open Nautilus, Firefox and Terminal by clicking on their icons
5. The mouse cursor turns to circle. After 10-15 seconds, some window will appear

After about one minute opening any of these apps will open immediately, as expected. If I logout and login to Wayland the issue is not present. If I logout and login into X11 the issue can be reproduced, so it is not related to boot but to login. If I uninstall nvidia drivers the issue is gone.

It might be an issue with mutter or gnome-shell.

$ apt list nvidia-driver-535 mutter gnome-shell
