I'm having the same issue with Python and Elixir interactive console. Interestingly, this issue does not happen for Ruby which (I believe) has more complex output logic to the console. It started to happen only in newer ConEmu versions.

I'm having the same problem in Powershell 7.1.1 within ConEmu. No issues when running from the stock terminal.
