[Bug 1857449] Re: QEMU x86_64 -nographic full system breaks host Bash terminal line wrapping state after simulation ends, requires reset or "tput smam" to fix 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.

Status: New => Incomplete

Title:
QEMU x86_64 -nographic full system breaks host Bash terminal line
wrapping state after simulation ends, requires reset or "tput smam" to
fix it
Status in QEMU:
Incomplete
Bug description:
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.
