Simultaneous line feeding and scrolling doesn't work well with irb on tmux
See attached capture.
I just entered
1+1 doesn't matter, whatever can cause the same behavior)
The problem is that the line of the expression
irb(main):xxx:0> 1+1 will disappear when the window scrolls.
This is a bottom of the capture:
irb(main):041:0> 1+1 => 2 => 2 => 2 irb(main):044:0>
It should have been like following:
irb(main):041:0> 1+1 => 2 irb(main):042:0> 1+1 => 2 irb(main):043:0> 1+1 => 2 irb(main):044:0>
This behavior seems to appear only on tmux.
