For a new window created with screen -s, the number of lines displayed in the window is always limited (about 50 lines)，
Unable to display all contents completely. It is difficult to find compilation errors or information logs

Reproduce the issue by creating a new window with `screen -s` and checking how much terminal output remains visible. Start by tracing the terminal window's line-display or scrollback handling; done means compilation errors and log output are no longer limited to about 50 lines.
