Prompt is printed twice when exiting nano

[anthonyvdotbe]

"OpenSSH for Windows" version
7.7.2.2

Server OperatingSystem
Raspbian GNU/Linux 9 (stretch)

Client OperatingSystem
Windows 10 Pro (version 1809)

What is failing
To reproduce:
. run ssh pi@foo
. enter "nano"
. press Ctrl+X to exit nano

At this point, the prompt is printed twice.
I have also tried with $env:TERM = 'xterm', but this didn't help.

Expected output

pi@foo:~ $ nano
pi@foo:~ $ 

Actual output

pi@foo:~ $ nano
pi@foo:~ $ pi@foo:~ $

Not sure if this helpful, but when connecting with -vvv, the actual output is as follows:

pi@sardien:~ $ nano
pi@sardien:~ $ debug2: client_check_window_change: changed
debug2: channel 0: request window-change confirm 0
debug3: send packet: type 98
pi@sardien:~ $ debug2: client_check_window_change: changed
debug2: channel 0: request window-change confirm 0
debug3: send packet: type 98

I get this leaving htop and also after clear

I get the same behavior when leaving htop, nano or using clear on build v7.9.0.0 when connecting to a Debian system.

I've tested this with version 8.0 and is still has the same issues. Additionally, this bug also appears when exiting or detaching a screen session.

[gadiel]

can confirm, it happens in both, powershell 5 and powershell 7 core lts.

Can also confirm, after using clear, htop and nano the terminal prompt is displayed twice and characters aren't displaying properly

@vlOd2 - This issue is fixed as part of PR shipped into V8.6. Can you please test your scenario with Win32-OpenSSH V8.9 / V8.6.

@bagajjal
The issue still persists. I do not know how to check the version, but I uninstalled the one from the settings and installed the latest v8.9 MSI file. I also changed my path just to be safe. The problem still persists.

@bagajjal
I can send you a recording...

[bagajjal]

@vlOd2 - You can check the SSH version number using ssh -V.

[vlOd2]

@bagajjal
OpenSSH_for_Windows_8.9p1, LibreSSL 3.4.3

[vlOd2]

@bagajjal
Also when using tmux, the problem is gone. Weird, maybe because tmux uses a different shell?

[vlOd2]

OpenSSH is unusable with this behaviour, the prompt becomes glitchy after using any terminal "fullscreen" app, or just by using clear

This still happens with ssh version OpenSSH_for_Windows_9.2p1, LibreSSL 3.7.2
