crictl exec prints weird characters

[Random-Liu]

# crictl --runtime-endpoint=/var/run/dockershim.sock exec -i -t 0382fd52f750f /bin/sh
/ # ^[[64;5Rls
ls
bin              kube-dns-config  root             tmp
dev              lib              run              usr
etc              media            sbin             var
home             mnt              srv
kube-dns         proc             sys
/ # ^[[64;5Rls
ls
bin              kube-dns-config  root             tmp
dev              lib              run              usr
etc              media            sbin             var
home             mnt              srv
kube-dns         proc             sys
/ # ^[[64;5R

This happens to both cri-containerd and dockershim.

/cc @feiskyer Any idea why this happens?

Not sure what's wrong. Are you pressing random keys in exec console?

[Random-Liu]

@feiskyer Nope.

Note that I'm exec into kubedns.

[Random-Liu]

Close by mistake.

I see this again today when crictl exec into calico-node.
