If I run `make run-qemu` under a Wayland compositor (tested with both
Sway and Weston), I get a Wayland protocol error ("invalid object 0")
and QEMU exits. It appears that there is a problem with
wayland-proxy-virtwl. I get the following error from foot:

warn: main.c:437: 'C' is not a UTF-8 locale, falling back to 'C.UTF-8'
warn: config.c:3520: no configuration found, using defaults
Fontconfig warning: no <cachedir> elements found. Check configuration.
Fontconfig warning: adding <cachedir>/var/cache/fontconfig</cachedir>
Fontconfig warning: adding <cachedir prefix="xdg">fontconfig</cachedir>
err: wayland.c:1714: no compositor
err: wayland.c:2248: failed to flush wayland socket: Connection reset by peer

And the following from wayland-proxy-virtwl:

2025-07-20 02:14:48.638 wl-proxy [WARNING]: Error handling client: Invalid_argument("invalid bounds in Cstruct.LE.get_uint32 [0,0](4096) off=0 len=4")

In case it matters:

- This is with some patches to allow use of TCG and others for
PipeWire. I highly doubt either set are relevant here.

- I tested this with both Sway and Weston. Each was added to
img/app/shell.nix so that it would be available in the nix-shell
environment. Both ran nested under the X11 session provided by
Qubes OS.
