  • Your Windows build number: (Type ver at a Windows Command Prompt)
    Microsoft Windows [Version 10.0.16199.1000]

  • What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)
    After executing a number of Linux commands, I scroll-up to review what I type. The history displayed is limited and only scrolling one page.

  • What's wrong / what should be happening instead:
    Seems like buffer history it's been erase or truncated so when you scroll-up only a limited number lines are displayed back. It should display all commands with results of what I've done.

You previously ran apt in that console window, right?

This is #1984 IIRC

No! Could be any command that returns over one page on screen. You still can't page-up or scroll up to see the content.

"cat /etc/inputrc" returns over one page on screen. I commanded "df -h", "cat /etc/inputrc", and then scrolled screen up;

Nope, it's not about returning more than one screen of content. apt install sets the scroll margins in a very particular way, or cleans then in a certain way that conhost doesn't clean up properly. I'm sure there are other applications that do this too, but I know for a fact that I can repro this with apt install.

Hum! I'm currently trying to rebuild my Windows 10 Bash subsystem manually. It became a little unstable as it gave an error (0x80070091) when trying both uninstall and install.

I will update this incident later!

I also notice that this phenomenon appears only after running "apt install".

Thanks! You're on the Creator's Update, and I think a patch for this issue is available in Fall Creator's update, which should be rolling out tomorrow, so let me know if updating to the latest build doesn't fix this!
