If I use a build introduced in PowerShell/openssh-portable#338 then PowerShell 5.1 is also affected. Shall this hold that PR back?

Are you sure it's win32-openssh ssh client issue?
Have you tried the other ssh clients (WSL, Putty)?
I didn't see this issue when I tried to login from win10 machine to Ubuntu 16.04.5 LTS

I see this on roughly 80% of connections to all servers. It's probably a clientside buffer reuse issue, not a server issue.

bagajjal PuTTY and the SSH from Git Bash works with the same servers without issue. If you are not able to reproduce it, would you like a
Vagrantfileshowing the issue? I can try to come up with one.There is some interesting issue with one of the servers. Part of MotD is duplicated. Not sure if this helps debugging.

Franklin Yu (@FranklinYu) - After multiple retries, I am able to repro the issue.
Will try to fix it for the next release.

Any updates?

I get a random nr of motd between 1-3.

This also happens when the alternate screen buffer is exited (like when vim is closed.)
