Describe the bug

Measuring pixel by pixel on the original image (2836 px wide):

Window center: x = 1418
Search field: spans from x = 1083 to x = 1700, so its center sits at x ≈ 1391
Offset: ≈ 27 px to the left of the window's true center
In other words, the field is only visually "centered" relative to the space between the icons on the left and the window controls (minimize/maximize/close) on the right — not relative to the full window width. Since the icon area on the left is smaller than the controls + avatar area on the right, the result is this subtle leftward offset. To actually center it relative to the window, the input would need to be pushed ≈ 27 px to the right (or positioned with left: 50%; transform: translateX(-50%) instead of relying on the current flex layout)

To reproduce

• Enable the vertical tab layout
• Note the search bar isn't quite centered

Is this an issue only in Warp?

Yes, I confirmed that this only happens in Warp, not other terminals.

Here's what I found while triaging this issue:

The screenshot and measurements provide enough evidence to route this as a vertical-tabs header layout bug. The search field appears to be centered within the available toolbar space rather than the full window width.

Maintainer details

I concluded that the vertical-tabs title bar search field appears horizontally centered within the remaining toolbar space rather than centered against the full window width..

Triage summary

The report describes a visual alignment issue in the vertical-tabs header: the top search field appears about 27px left of the full window center on macOS. The screenshot, pixel measurements, Warp version, OS, and minimal repro are enough to treat this as highly reproducible.

Likely area

This routes to the vertical-tabs/window layout and search/header UI. In app/src/workspace/view.rs, the vertical-tabs title bar is built as a flex row with a left toolbar group, a shrinkable center slot containing render_title_bar_search_bar, and right controls. The search field is centered within that middle slot rather than positioned against the full window bounds, so asymmetric side controls, avatar/settings controls, and platform traffic-light spacing can produce the reported visual offset. app/src/util/traffic_lights.rs is relevant because platform-specific traffic-light reservation affects the side spacing in the same header.

Duplicate check

I checked all open issues and recently closed issues for overlapping vertical-tabs/search/centering symptoms. I found related vertical-tabs and search issues, but not two or more existing issues with this same top search-field centering behavior, so this is not being marked as a duplicate.

This is my automated analysis and may be incorrect. A maintainer will verify the details.
