This was fixed upstream in byobu v6.14 (February 2026) via PR #68. The
root cause was that byobu_prompt_runtime was writing to stderr, causing
bash to miscalculate the prompt line length and corrupting readline
cursor positioning. The fix is a one-character change:
`byobu_prompt_runtime 2>&1` in the PS1 definition.
Ubuntu users on affected releases can work around it immediately by
running `byobu-disable-prompt`, or by manually changing the
`$(byobu_prompt_runtime)` call in /usr/share/byobu/profiles/bashrc to
`$(byobu_prompt_runtime 2>&1)` until the Ubuntu package is updated to >=
6.14.
Marking Fix Released.
