Stuck looking up/down

In pre5 the game boots and runs fine but I am stuck looking at the ground. If I invert the mouse via the in game settings I look at the sky. When i move the mouse I spin left or right, but never look up (or down when the mouse is inverted).

I have forced a crash and attached my log.

Result is the same when using a mouse or the touchpad. Using an external monitor as opposed to my laptops monitor also does not appear to make a difference. The mouse cursor is not hidden, so this may be a bug with my wm, although in my tests sway is compliant with the wayland protocol. Perhaps a xwayland bug.

Previous versions of minecraft crashed at boot (MC-126508) so I cannot regress.
