Issue still occurs on latest mainline kernel without nvidia proprietary drivers. Attached another picture as logging is shutdown when issue occurs. The attached display is only connected to the dedicated GPU and is not outputted to at all in this configuration.

I've attached a picture because the error message does not show up in any logs. Possibly a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872817, though the other user did not mention the same symptoms.
