I haven't seen such behavior, except for the probably obsolete https://bugzilla.gnome.org/show_bug.cgi?id=730763. Mind you, I was using VTE and gnome-terminal from git, the rest from Yakkety.
Does this lag of 3-4 seconds appear suddenly at one point, or does the performance constantly degrade over time? One more thing I can think of is rewrap on resize, it's a slow operation. If you have an enormous scrollback buffer (maybe a million lines or more), resizing could be this slow. However, if I understand you correctly, you also see delays when you don't resize but normally use a terminal (execute commands and such). Am I right? If so, we can exclude this possibility. ** Bug watch added: GNOME Bug Tracker #730763 https://bugzilla.gnome.org/show_bug.cgi?id=730763 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1681336 Title: terminal shows window contents video with lag and glitches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1681336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
