How do I further troubleshoot this?

The problem was the Maliit-Keyboard I installed. I installed from apt.

It caused the following x11 error to be reported:

Removing Maliit resolved the problem.

I’ve reported the bug to apt: https://bugs.launchpad.net/ubuntu/+source/maliit-keyboard/+bug/2039721
