Same issue on arch linux, using the sway window manager (wayland).

Workaround works.

This doesn't belong in Java Edition's issues anyways.

Confirmed - I'm pretty sure this has been the way it is for ages though.

Looking up this error online, this might be a driver issue. Could you try updating your graphics driver and try again?

Edit: Nevermind. See MC-128302

Maybe the issue is the structure itself? Did it work in 1.12.2? Are the spawn conditions for monsters being met?
