Screen clear does not work properly when starting Copilot — previous output remains visible #7
Description
Description
When starting Copilot, the screen is not properly cleared. Previous terminal output remains visible on screen, and the user has to wait until new output overwrites it line by line. It appears the clear/reset escape sequences are not being handled correctly in the Swift terminal emulator.
Expected Behavior
When a clear screen command is issued (e.g. \e[2J, \e[H\e[2J, or similar ANSI escape sequences), the entire visible screen should be erased immediately and the cursor should be repositioned, just like in a standard terminal emulator.
Likely Cause
The terminal emulator may not be correctly processing one or more of the following ANSI escape sequences:
\e[2J— Erase entire screen\e[3J— Erase scrollback buffer\e[H— Move cursor to home position
Alternatively, the screen buffer may not be resized or flushed properly after a clear, leaving stale content visible until it gets overwritten by new output.
