driver-manager had a priority tie for QEMU virtio-gpu (vendor 0x1AF4, class 0x03): redox-drm (generic class @60) vs virtio-gpud (@60). If virtio-gpud won, it registered display.virtio-gpu (VT scanout only) and never provided /scheme/drm/card0, starving KWin/the compositor. redox-drm had priority-61 entries for Intel and AMD but none for VirtIO. Add a priority-61 redox-drm entry for vendor 0x1AF4 class 0x03 (subclass omitted — QEMU virtio-gpu is subclass 0x80) so the VirGL path deterministically binds redox-drm and gets a real DRM card0. virtio-gpud remains as fallback.
