Hi, * Jochen Sprickerhof <[email protected]> [2025-12-03 22:27]:
Steps to reproduce:debvm-create -- --hook-dir=/usr/share/mmdebstrap/hooks/useradd \ --include=linux-image-generic,xserver-xorg-core,xserver-xorg-input-libinput,lightdm,icewm,xterm,neovim,tmux debvm-run -g Inside the VM start an xterm, a tmux and inside: vi -c 'set spell' <(echo bla blaj) Running the same vi command outside of tmux will underline the spelling errors but not inside tmux. You can also run debvm-create -r testing or trixie to verify that tmux 3.5a-3 works and update just tmux to see that it is enough to trigger the behaviour change.
This is due to: https://github.com/tmux/tmux/commit/7499d925da697498b7ee69b0effaa8b5176a50bfI am unsure if this is a better behaviour then before given that tmux announces Smulx support. As a workaround I switched to a terminal emulator that supports it.
Cheers Jochen
