Environment

Windows build number: 19033.1
Windows Terminal version (if applicable): 0.7.3291.0

Any other software?
zsh

Steps to reproduce

  • I open a new terminal window running Ubuntu 18.04, using zsh as the shell
  • I runrepeat 100 echo wat (not something you would actually want to do, but sufficient to demonstrate the issue)
  • I then run printf "\033c"

Expected behavior

A clear terminal, with no previous output that you can scroll back up to.

Actual behavior

You can scroll upwards to view the output of previous commands. This can make working in the terminal a bit cumbersome when you are running a command with a long output (e.g. a suite of tests), as it then becomes difficult to scroll back through the output without accidentally scrolling into the output of previous commands.
