   In that case, I suspect that you're hitting the screen size change buffering issue in PowerShell/openssh-portable#426. Even though it doesn't look like the screen size is changing, less is turning on the "alternate buffer" which reports a window resize. OpenSSH, until pull 426, had trouble handling the resize event.

   If you run OpenSSH 8.1 from the win32-openssh releases page, does it go away?

    Downloaded OpenSSH 8.1 from that page and tried it, the problem still exists. By the way, ssh version of my remote server is "OpenSSH_7.4p1, OpenSSL 1.0.2k-fips 26 Jan 2017". Should I also upgrade that one?

    Three answers will help the Microsoft (and other) people:

    • Does this happen as you scroll up and down? Or initially when less first displays the file?
    • What happens when you tell less to redraw the screen?
    • What is the value of the TERM environment variable on the system that is actually running the less program?

    I apologize. The pull request that fixes the buffering/repeat issue merged on April 2, 2020 but the 8.1 release came out in Dec 2019. I do not know why I thought it might help. 😄

    TypicalSEE There's now an OpenSSH 8.6 (https://github.com/PowerShell/Win32-OpenSSH/releases/tag/V8.6.0.0p1-Beta), mind trying that one? We think that might have the fix
