When using tmux integration, "Arrange Split Panes Evenly" converts vertical split to horizontal split
Bug report
Thanks for filing an issue! Please answer the questions below so I can help you.
- iTerm2 version: Build 3.4.21
- OS version: macOS Ventura 13.6.1
- com.googlecode.iterm2.plist
- Attach a debuglog.txt
Detailed steps to reproduce the problem
- Open an iTerm2 window with tmux integration (tmux -CC)
- Split the window vertically using menu item Shell->Split Vertically...
- Resize the vertical split so that the two sides aren't equal (this step may be unnecessary)
- Select Window->Arrange Split Panes Evenly
- Notice that the window now is split horizontally instead of vertically.
What happened
The window split changes from vertical to horizontal
What should have happened
The split should have stayed vertical with the two halves resizing to the equal sizes
Note that this behavior does not occur in a regular non-tmux iTerm2 window.
