This was broken intentionally in order to fix another bug which is not fixable and not even workaroundable otherwise. See https://bugzilla.gnome.org/show_bug.cgi?id=754596. Although, as discussed there, we are aware of problems that we introduced and we have a few ideas how to improve (that is, partially revert) the behavior.
In order to help move forward, could you please share your app (or better, a tiny proof of concept, just the necessary steps extracted that demo the problematic behavior)? ** Bug watch added: GNOME Bug Tracker #754596 https://bugzilla.gnome.org/show_bug.cgi?id=754596 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1678271 Title: Background color erase (bce) is broken Status in gnome-terminal package in Ubuntu: New Bug description: I'm running my ncursesw application, displaying a black background. When the screen or a region scrolls up by one line, empty areas of the screen in the newly visible line show the default white background of gnome-terminal. If I remove the bce capability from the Terminfo for that terminal type, the problem goes away. This workaround involves: "infocmp xterm-256color > xt.ti" to get the Terminfo data in text format. Editing xt.ti and removing "bce, " on the 3rd line "tic xt.ti" to compile this text to Terminfo again. Without sudo that ends up in ~/.terminfo, overriding the system's entry, and with sudo it would overwrite the system's Terminfo entry for that terminal type. Another workaround would be to use a different terminal type without bce, like TERM=screen, but removing bce is better because that leaves other capabilities intact.
