Comment 5 for bug 2046360

mantic verification

I used mutter from mantic-proposed:
andreas@nsnx2:~$ apt-cache policy mutter
mutter:
  Installed: 45.2-0ubuntu2~really45.0
  Candidate: 45.2-0ubuntu2~really45.0
  Version table:

     45.2-0ubuntu1 500 (phased 0%)

I installed gnome-session gnome-shell-extensions. I did not install budgie, because the test plan at https://wiki.ubuntu.com/DesktopTeam/TestPlans/Mutter says it's not needed for 23.10.

Each login, I selected a different session from this list: GNOME, GNOME Classic, Ubuntu, Ubuntu on Xorg.

In each session, I did:
- play 4k youtube video in full screen in firefox and chrome. For the next steps, I left firefox playing that video while conducting the other checks
- verified that firefox was using hardware acceleration (chrome isn't, that's known)
- sent a notification via notify-send, observed it was displayed
- did a large file copy with the file manager. First, locally, then over the network using SMB.

I did not observe any stuttering during these verifications, nor any other ill effect.

The hardware this was tested on is a ThinkPad X1 Carbon Gen 10 with an Intel Alderlake_p (Gen12) video system.
