CSI 3 J comes from xterm, where it only clears the scrollback buffer. VTE
(gnome-terminal, xfce-terminal, ...) behaves likewise. Putty also follows that
behavior.
See
https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h3-Functions-using-CSI-_-ordered-by-the-final-character_s_
:
CSI Ps J Erase in Display (ED), VT100.
Ps = 0 ⇒ Erase Below (default).
Ps = 1 ⇒ Erase Above.
Ps = 2 ⇒ Erase All.
Ps = 3 ⇒ Erase Saved Lines, xterm.
So, CSI 2 J erases all the screen, but not the scrollback buffer, while CSI 3 J
erases the scrollback buffer, but not the screen.
