Bug description:
  I originally observed this on Debian packaged qemu 5.2 at

  Today I checked out the latest git source at
  Sun, 13 Dec 2020 19:21:09 +0900
  and configured the source as follows:

  ./configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/lib/qemu \
   --localstatedir=/var --disable-blobs --disable-strip --localstatedir=/var \
   --libdir=/usr/lib/aarch64-linux-gnu \ 
   --firmwarepath=/usr/share/qemu:/usr/share/seabios:/usr/lib/ipxe/qemu \ 
   --target-list=aarch64-softmmu,arm-softmmu --disable-werror \ 
   --disable-user  --enable-gtk --enable-vnc
  then executed "make" on an ARM64 (not an x86_64) host,
  running the latest Debian testing.

  I did the following commands on an arm64 host with the Debian Installer Alpha 
3 at


  rm -f $IMAGE
  qemu-img create -f qcow2 -o compat=1.1 -o lazy_refcounts=on -o 
preallocation=off $IMAGE 20G
  cd /var/tmp
  cp /usr/share/AAVMF/AAVMF_VARS.fd .
  $HOME/qemu-git/qemu/build/qemu-system-aarch64 \
      -display gtk -enable-kvm -machine virt -cpu host -m 3072 -smp 2\
      -net nic,model=virtio -net user -object 
rng-random,filename=/dev/urandom,id=rng0 \
      -device virtio-rng-pci,rng=rng0,id=rng-device0 \
      -drive if=virtio,file=${CDROM},index=1,format=raw,readonly=on,media=cdrom 
if=pflash,format=raw,unit=0,file=/usr/share/AAVMF/AAVMF_CODE.fd,readonly=on \
      -drive if=pflash,format=raw,unit=1,file=`pwd`/AAVMF_VARS.fd

  Then 4 arrow keys on the physical keyboard are received as just "^[".

  This symptom was not observed on qemu-system-x86_64.
  This symptom was not observed with virt-manager on my arm64 host, neither.
  This seems unique to -display gtk of qemu-system-aarch64.
