Public bug reported:
QEMU 4.2.0 compiled from source, Ubuntu 19.10, open a fresh new gnome
terminal.
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.

Apparently the code you run (BIOS?) is sending the DECRST control sequence to the terminal, which disable the auto-wrap mode flag.
Looking at the detailed explanations on https://github.com/mattiase/wraptest I'm not sure how QEMU can save/restore this flag.

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 :-(

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.
