Core dump on wayland (swaywm)

I'm using the Archlinux aur package with wayland (sway wm) but it crashes with the following error:

```
[wayland-client error] Attempted to dispatch unknown opcode 0 for wl_shm, aborting.
[1]    3407478 IOT instruction (core dumped)  postsack
```

I can launch it with `WINIT_UNIX_BACKEND=x11 postsack` but that's not ideal.
