Problem description

Scrolling up through a program such as man in tmux leads to sympathetic scrolling in horizontally neighbouring panes. I cannot reproduce the issue over SSH or in terminal emulators running on Xvnc, so I assume the issue lies in Termux's terminal emulator.

Steps to reproduce the behavior.

Assuming tmux and man are installed and tmux has its default key bindings:

  1. Start tmux.
  2. Populate the pane with text, e.g. ls $PREFIX/bin.
  3. Split the screen horizontally, i.e. CTRL-b %.
  4. Run man tmux.
  5. Scroll down by pressing DOWN a few times.
  6. Scroll up by pressing UP a few times and observe that both panes scroll up simultaneously.

What is the expected behavior?

There should be no sympathetic scrolling.

System information

  • Termux application version: 0.118.0
  • Android OS version: 10, 11
  • Device model: Huawei MatePad 11, Samsung Galaxy Note 3

According to @pierreyves-lebrun comment, it seems to be an upstream problem. Hence, closing.

Fixed: Make ScrollDown escape respect margins

SD sequence (`${CSI}${N}T`) was scrolling the whole width
 of the terminal instead of just between the margins.
Fixed that.

Fixes termux#2576 where in tmux scrolling one of several
 side-by-side panels down resulted in all visually scrolling.

RI sequence (`${ESC}M`, move cursor up 1 line) was doing the same.

The above PR definitely fixes the problem for me, and this is how de-facto standard xterm behaves. (And apparently how VT510 behaved too.)
So, if Mac terminal really doesn't handle it this way, IMO it is broken.
