[Bug 1500228] Re: When scrolling back up some of the bottom comes up as a sort of sleeve

[Egmont Koblinger]

One more question: Do you have anything like tmux, screen, ssh, or
similar additional layer of software running? Or you just open the
terminal, type "man dpkg" and it's buggy?

Title:
  When scrolling back up some of the bottom comes up as a sort of sleeve

Status in gnome-terminal package in Ubuntu:
  New

Bug description:
  I have recently noticed that when viewing a manpage in gnome-terminal
  that if scrolling down, when I scroll back up again some of the bottom
  part of the page comes up too sort of like a sleeve. I have attached
  some example screenshots, so I ran 'man dpkg' and this is what it
  looked like initially dpkg_man_top1.png, but when I scrolled down to
  the bottom of the page and then back up again to the top, the top
  looked somewhat different as you can see: dpkg_man_top2.png. Now, it
  wouldn't matter where I had scrolled down to, nor where I had gone up
  to, the effect witnessed would have been the same.
