width of unicode chars affecting lines in tmux pane to the right

mckellygit commented 2 years ago

What Operating System(s) are you seeing this problem on?

Linux X11

WezTerm version

wezterm 20220421-183827-26500c67

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

If I create 2 tmux panes side-by-side and then I edit a unicode file with vim in the left side pane, the right side pane is no longer correct, with some lines shifted right some chars.

To Reproduce

create 2 tmux panes side by side, then in the left pane open unicode file with vim and notice right pane lines are moved some and no longer correct.

Expected Behavior

other terminals (kitty, alacritty, st) do not seem to have this issue.

Anything else?

Thank you for wezterm, it is awesome. A line to put into a file for testing ? Comment[hi]=काटें एवं चिपकाएं इतिहास यूटिलिटी

Please capture a terminal recording:

Launch wezterm. If possible, please use 80x24 for the terminal dimensions as it helps to keep things smaller and easier to manage.
Inside that terminal run wezterm record to start a recording session.
Run through your reproduction steps: launch tmux and repro the problem. Pause for a few moments with the problem manifesting, then exit tmux.
Then type exit
You should see a message like:

*** Finished recording to /var/tmp/wezterm-recording-sF6B3u.cast.txt

Attach the file that it produced to this issue.

The file is an asciicast (compatible with https://asciinema.org/) and can also be replayed using wezterm replay.

The terminal recording allows me to replicate what is being sent to the terminal without requiring me to install the same applications as you and replicate your configuration for everything.
