  3. type "clear" to clear the terminal

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?

@Y0rg0 commented on GitHub (Jan 4, 2024):

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

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...
