Bug #15944: Simultaneous line feeding and scrolling doesn't work well with irb on tmux
https://bugs.ruby-lang.org/issues/15944

* Author: hasumikin (hitoshi hasumi)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.7.0dev (2019-06-17T21:05:43Z trunk 39a8c71424) [x86_64-linux]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
See attached capture.

I just entered `1+1` repeatedly.
(`1+1` doesn't matter, whatever can cause the same behavior)

The problem is that the expression `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.

[ruby-core:96260] [Ruby master Bug#15944] Simultaneous line feeding and scrolling doesn't work well with irb on tmux

[mame]

Issue #15944 has been updated by mame (Yusuke Endoh).

Status changed from Open to Closed

Thank you for the reporting.  It does not reproduce now.  IRB is now actively developed, so I guess it is already fixed.  If not, feel free to reopen.

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):043:0> 1+1
=> 2
irb(main):044:0>
```
