Comment 6 for bug 945069

@Ionut, thanks for posting back. Just the ~/.byobu/keybindings.tmux was not enough for me, I also had to add the first line ("set-window-option -g xterm-keys on") to my .tmux.conf which I actually found at ~/.byobu/.tmux.conf. With those two, byobu now works splendidly with the tmux backend.

I'd suggest we could close this ticket as it seems like it's more of a design change on behalf of the byobu author rather than a bug.
