Public bug reported:
source package: https://packages.ubuntu.com/en/source/jammy/tmux
this was a bug in tmux 3.2a -- it has since been fixed on tmux master
here is my system information:
```console
$ dpkg -l | grep tmux
ii tmux 3.2a-4build1
amd64 terminal multiplexer
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04
Codename: jammy
```
you can reproduce this pretty easily with:
```bash
tmux -V
tmux new-session -d -x 20 -y 20 bash
tmux send-keys 'tput cols'
tmux send-keys 'Enter'
sleep 1
tmux capture-pane -pt0 | grep -Eo '^[0-9]+'
tmux kill-session
```
on 20.04, I get the following:
```console
$ bash t.sh tmux 3.0a
20
```
on 22.04 I get the following (my parent window is 118 wide):
```console
$ bash t.sh
tmux 3.2a
118
```
I've gone ahead and bisected to find the patch that's needed to fix this -- it
was originally committed here:
https://github.com/tmux/tmux/commit/df3fe2aa72da0555106c6187e750418f0e59d901
applying that to the packaging of 3.2a should be pretty straightforward,
I've verified that applying it fixes the problem:
```console
$ git checkout 3.2a
$ git cherry-pick df3fe2aa72da0555106c6187e750418f0e59d901
$ ./autogen.sh >& /dev/null && ./configure --prefix=$PWD/prefix >& /dev/null &&
make -j5 >& /dev/null && make install >& /dev/null &&
PATH=/tmp/tmux/prefix/bin:$PATH bash ../t.sh
tmux 3.2a
20
```
so all that should be needed is to apply that patch:
```diff
commit df3fe2aa72da0555106c6187e750418f0e59d901
(refs/bisect/skip-df3fe2aa72da0555106c6187e750418f0e59d901)
