Sounds really interesting. Any chance of this being the same as https://bugzilla.gnome.org/show_bug.cgi?id=730763 ?
Could also indeed be an issue related to Cinnamon. Can you try to reproduce under a different WM? Can you download vte-0.38.3, compile with "./configure --enable-debug; make" and launch with "./src/vte-2.91", does it also misbehave? If so, start with "VTE_DEBUG=all ./src/vte-2.91", do you see the entire window flashing up in red for each Shift+PageXx keypress, and is the result still buggy? Is there output produced between the Shift+PageXx keypresses, or is it irrelevant? ** 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/1460062 Title: Scrollback with Shift-PageUp Shift-PageDown does not refresh screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1460062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
