Ah, thanks for looking into this and identifying it to guest code Philippe. I don't know much about terminals, but yes, they are such archaic interfaces, maybe there is no API for it :-(

If you print 1000 = chars on the host terminal, then they do wrap around the end of the terminal: printf "=%.0s" {0..1000} However, if you first run QEMU: x86_64-softmmu/qemu-system-x86_64 -nographic and then quit it in any way, e.g. with Ctrl + A, and then re-run on the host terminal: printf "=%.0s" {0..1000} then the signs don't wrap around anymore, they just go "off the terminal to the right". This can be fixed with either: reset tpam smam but unfortunately those don't work in tmux for some reason: https://github.com/tmux/tmux/issues/969 I consider this buggy behavior, QEMU should restore the original terminal state if possible.
