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

 

Vte used to contain such drawing bugs, but we fixed all the known ones
about 1.5 years ago and I haven't seen any display corruption like yours
since then; nor have seen any other user complaining (I keep an eye on
official gnome-terminal bugzilla, Ubuntu, Debian and Red Hat
bugtracker).

I use Wily beta and cannot reproduce your issue.

This gives me a hunch that it's probably something wrong with Gnome3
staging, or perhaps your X driver or something like that.

But of course it can be a gnome-terminal/vte bug which only occurs on
your computer.

Reproducing in a VM with Wily: if you can reproduce then that's
definitely helpful; but if you can't then that means nothing: it still
could be buggy with Wily directly on your computer.

Are you planning to update any time soon? My recommendation is to wait
until you upgrade and use mainstream Wily (no Gnome3 staging) and still
can reproduce it there. If it's still an issue I'd be happy to start
debugging it with you, but I would first like to exclude the possibility
that something in Gnome3 staging is the culprit.

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

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.
