[Y0rg0]

Windows Terminal version

1.19.3172.0

Windows build number

10.0.19045-3803

Other Software

No response

Steps to reproduce

1. open the Terminal
2. type any command that produces output in the terminal - e.g. a simple "dir" or "cd C:" will do
3. type "clear" to clear the terminal

Expected Behavior

"clear" to always clear the previous output...

Actual Behavior

cursor will be positioned at the top of the inner window, but the previous output still is visible below
(this does not happen all the time, but mostly)

Hmm. I can't seem to repro this. Do you have any more detailed repro steps? How are you launching the Terminal? What shell are you using (PowerShell? CMD? Bash/zsh/fish/etc)? Do you have anything in your shell settings/profile that might be at play here? Something that attempts to resize the window perhaps?

This problem only occurs when the mentioned output only fills the screen partly, e.g. by just typing "cd" -- which typically only produces one or two lines of output; if I do a "dir" instead which fills the whole terminal window, "clear" always works... btw: this is for normal CMD shell.

huh. Where did you get clear from/? That's not a built-in CMD intrinsic like cls is, and there isn't a clear.exe that ships inbox.

What is clear? What about to use cls ?

 C:\> clear
'clear' is not recognized as an internal or external command,
operable program or batch file.

 C:\> where clear.*
INFO: Could not find files for the given pattern(s).

C:\Users\xxxx>where clear
C:\Program Files\Git\usr\bin\clear.exe

excellent find - and "cls" works better -- thank you :)

Yep, that makes sense. Thanks for following up!

to my defense :-)
I work in Windows and Linux, so I am used to use commands that work in both universes:
"clear" does this (normally...), but "cls" is not known in Linux...
