Actually the bug just happened to me and now I can see "drmModeAtomicCommit: Invalid argument" in my logs now. So it turns out I am experiencing this bug.

I will try the work around posted at the top of the first post. I will be very happy if this fixes the problem!

[ Workaround ]

Add to /etc/environment (in Ubuntu 22.04):

  MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0

or in Ubuntu 22.10 and later:

  MUTTER_DEBUG_FORCE_KMS_MODE=simple

and then reboot.
