Please uncoment https://github.com/PowerShell/openssh-portable/blob/4ee8dc64982b62cd520417556515383908091b76/contrib/win32/win32compat/shell-host.c#L804. To fix:

>2) when ssh client window is resized it clears everything and gives a blank screen.

For me ssh-shellhost.exe for amd64 from https://github.com/PowerShell/Win32-OpenSSH/issues/1222#issuecomment-409052375 works well. Were can I find ssh-shellhost.exe for 386?

@abakum what OS versions do you have running on the client and the server?

abakum commented 6 months ago

Microsoft Windows [Version 10.0.14393] on same PC server and client

tgauth commented 6 months ago

Starting with Windows 10 Build 18309, ConPTY should be supported so ssh-shellhost is not needed. Is updating the OS an option?

Also, all releases have 386 binaries within OpenSSH-Win32.zip

abakum commented 6 months ago

VScode used winpty

tgauth commented 6 months ago

Are you running SSH through the VSCode extension?

abakum commented 6 months ago

No, but VSCode does not offer to update the Windows version - it just uses what works \8^)
