Comment 10 for bug 1500228

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.
