If my `git bisect run` script worked, I've found the commit
introducing this issue:

4c993d8ab5473334e9d4155faa913476ada39069 is the first bad commit
commit 4c993d8ab5473334e9d4155faa913476ada39069

    qemu: add qemu vga devices caps and one cap to mark them usable

    QEMU_CAPS_DEVICE_QXL          -device qxl
    QEMU_CAPS_DEVICE_VGA          -device VGA
    QEMU_CAPS_DEVICE_CIRRUS_VGA   -device cirrus-vga
    QEMU_CAPS_DEVICE_VMWARE_SVGA  -device vmware-svga

    QEMU_CAPS_DEVICE_VIDEO_PRIMARY  /* safe to use -device XXX
                                     for primary video device */

    Fix a typo in qemuCapsObjectTypes, the string 'qxl' here
    should be -device qxl rather than -vga [...|qxl|..]

bisect run success

FWIW, problem is not reproducible against the parent commit
