This is a beta feature where Claude code draws the interface on the terminal’s alternate screen buffer like vim or htop. I believe it’s not the default because there are some potential compatibility issues deepening on your terminal setup. I’ve found it to be a nice improvement. It also fixed the issue where copy-pasting selected text from the terminal creates unwanted line breaks.
Claude Code is essentially a terminal emulator that runs on mature OSes with excellent support for this type of application. Why are they having difficulty implementing it?
