Three separate faults, each producing a black Moonlight stream:
- sunshine's wlr backend takes wlr-screencopy's dmabuf path, which on this
virtio-gpu returns empty buffers. Reproduced locally over 127.0.0.1, so it
is not the network or the client. Switch to kms capture.
- hypridle locked the session and cut dpms, blanking the captured output with
no console to unlock from. Disable it on this host.
- qemu picked the nvidia render node by readdir order, so virgl fell back to
llvmpipe. Pin renderD128 via the VM's args.
