This is not a bug in the library but rather an incompatibility between
the xterm* terminfo entries since ncurses 6.1 and several older terminal
emulators. It is rather unfortunate that nobody reported it (at least
not to the ncurses maintainers) before the buster release. :-(

In fact, it is the same as #905247.

Yep, that was only fixed in later versions of libvte[1].
Since so many older terminal emulators are affected, I guess we have to
disable the problematic feature in ncurses-base. If you want to do that
yourself, the following command should do the trick:
infocmp -x | sed 's/rep=[^,]*,//' | tic -x -
This writes a new compiled terminfo entry for $TERM under
$HOME/.terminfo (or /etc/terminfo, if you are root) which takes
precedence over the one in /lib/terminfo. You probably want to remove
it once a fixed ncurses-base is available.
