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. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to less in Ubuntu. https://bugs.launchpad.net/bugs/1500228 Title: When scrolling back up some of the bottom comes up as a sort of sleeve Status in gnome-terminal package in Ubuntu: New Status in less 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. --- OS Information: No LSB modules are available.
