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. ---Files-------------------------------- irb_on_tmux.png (170 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
