Create terminal split

Again, no idea what that is. Please be more specific.

[kidonng]

I assume "split terminal" is a common way to express the idea, but let me try to put it more specifically.

1. Concepts:

   kitty is capable of running multiple programs organized into tabs and windows. The top level of organization is the OS window. Each OS window consists of one or more tabs. Each tab consists of one or more kitty windows.

2. In the demo, I have one OS window, one tab in it (tab bar is hidden), and initially one kitty window.

3. As recorded in the bottom left corner, I press Command + Enter, which is the default shortcut to open a new (kitty) window on macOS.

4. A new kitty window appears, taking up the bottom half of the vertical space (the thin green line is the separator).

5. This bug appeared due to changes of window size.

If this sounds more confusing, I would like to kindly ask you to try reproducing it, or at least get familiar with (a similar) concept of Terminal multiplexer (I'm not using tmux or anything, it's just I can't find a credible source about this particular feature of terminal doing split windows).

[marlonrichert]

I know what a terminal multiplexer is, I just wanted what exactly you meant in your case, what you were using to split your terminal, so I can use the same to reproduce the problem. Thanks for explaining! This is all useful info.

[marlonrichert]

Can you run functions -t .autocomplete.down-line-or-select.zle-widget just before your final step to reproduce the bug? Then share the output here.

Closing, since I haven't heard back from @kidonng.
