Quick terminal splits get 1px out of sync with aggressive resizing

[JakeWharton]

I'm on macOS 14.7.1 (23H222) with Ghostty 9f75d93.

My full config is

initial-window = false
copy-on-select = true
window-save-state = always
background-opacity = 0.9
background-blur-radius = 5
window-step-resize = true
keybind = global:alt+grave_accent=toggle_quick_terminal
mouse-hide-while-typing = true
macos-option-as-alt = true

I tend to keep the quick terminal split into two panes. Aggressive resizing causes them to get 1px out of sync in terms of height:

split.mov

Hiding and re-showing the quick terminal fixes this misalignment.

This issue occurs regardless of the window-step-resize = true settings.

Well that is extremely bizarre. It's not like we're setting the pixel-level height of the view lol, this is just a SwiftUI-contained view hierarchy. I didn't confirm it yet but I certainly see it in the video. Also very odd that hiding and re-showing fixes it, I'll have to think about all that.

I just attempted to reproduce this in MacOS (14.6.1) and the default config and could not. It looks as expected, without the weird mismatch

With 1.0.0 release, I'm unfortunately still able to repro:

Thanks. I’ve done nothing to try to solve this yet. I haven’t yet been able to reproduce it.

[JakeWharton]

Yeah not a big deal. It's extremely low priority, and hopefully not even your problem but something in SwiftUI/AppKit or wherever. Mostly just confirming that I can still repro it with wildly-aggressive resizing (which is not at all like the resizing that I expect 99.99% of people to do). I don't even do such resizing normally–it was only when I was testing my TUI framework's parsing of in-band resizing notifications that caused me to discover it…

Not sure if related but had this splitting at title-bar with zero config [video is normal speed]. Funnily enough, could not replicate when resizing from the left side.

Here's another one.

shell-integration = zsh
cursor-click-to-move = true
