Hello Andreas,

I saw the same error on a 13th Gen Intel(R) Core(TM) i7-1370PE using the IOT release of jammy desktop.

I can confirm that installing mutter from jammy-proposed fixed the issue on my system.

$ uname -a
Linux amr-rplp-01 5.15.0-1034-intel-iotg #39-Ubuntu SMP Thu Jun 22 20:56:05 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.2 LTS

Now I have this mutter release:

$ apt list -a mutter
Listing... Done
