Well that sure is weird, and something I can't repro locally.

• Did this happen on 1.20/?
• Do other commands that might cause scrolling (something like a dir c:\windows\system32) work as expected?
• What is the output of chcp on your machine?

[b1xcy]

• it happen on 1.20
• almost all commands cause inability to scroll
• the output of chcp is Active code page: 65001(I have tried switching to 936 or 437, but neither has worked)
  It's interesting that after I enter chcp, I can scroll a little distance
  But this can lead to some display issues

[lhecker]

The fact that chcp behaves differently makes me believe that this must be a VtEngine bug, but after going through the conhost settings I could not find anything that may cause this.

Just to be sure, @b1xcy can you try to install the canary version from here? https://aka.ms/terminal-canary-installer
It should pick up your Windows Terminal settings automatically. Please let us know if the issue still happens then! (If it does, please feel free to uninstall it again.)

[b1xcy]

The Canary version still has this error(I hope my Chinese interface won't cause any inconvenience to you)
Only command prompt can generate such an error, neither PowerShell nor Windows PowerShell
Here is the Canary version settings.json

Is there anything in

• HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun
• HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun

?

• Show only one page #15669
• Terminal's scroll bar disappeared #15036

Thank you for your answer. I found that ansicon was running extra in HKEYTERENTVNet\Software\Microsoft\Command Processor\AutoRun.
This program caused scrolling failure.
