Steps to reproduce

Add a profile for Cygwin.

            {
                "commandline": "C:\\cygwin64\\bin\\bash.exe -l",
                "guid": "{09ff2493-xxxx-4ee9-xxxx-d7f90bb2xxxx}",
                "hidden": false,

Weird. Does this repro with the vintage console host, conhost.exe by any chance?

The same. The more number of lines the more possibility to reproduce this issue.

Please note that this issue cannot be reproduced by using ssh.exe in System32\OpenSSH\ with the conhost.exe. However, if using the same ssh.exe with bash.exe, it can be reproduced.
