Pre-submit checklist

• I have searched the existing issues and did not find an exact duplicate.
• I can reproduce this on the current stable release.

Warp version

v0.2026.03.18.08.24.stable_01

OS

Windows 11

Shell

PowerShell 7 (pwsh)

What happened?

On Windows with PowerShell, Warp prompt briefly shows the Git branch when the terminal/session initializes, then the branch chip disappears and only the path/time remain.

This is not a Git repository detection problem:

• git branch --show-current returns the correct branch.
• Warp also records the correct git_branch value internally.
• The branch can appear for a moment right after startup / session restore, then gets replaced by a prompt state without the visible branch.

In my case, the current repo is E:\workcode\fofa-frontend-v5 and the branch is feat/theme-light.

Steps to reproduce

1. On Windows 11, use Warp with PowerShell 7.
2. Go to Settings > Appearance.
3. Set Input type to Warp.
4. Open a Git repository.
5. Observe the prompt after startup / session restore.

Expected behavior

The Warp prompt should continue showing the current Git branch chip while inside a Git repository.

Actual behavior

The Git branch may appear briefly during initialization, but then disappears. After that, only other chips like working directory and time remain visible.

Additional details / evidence

• git branch --show-current returns the correct branch: feat/theme-light
• Warp docs say Warp prompt should support Git branch chips.
• I also noticed inconsistent local state where the UI can show Warp mode selected while persisted terminal pane state appears to flip back to Shell.
• Internally, Warp stores correct git_branch values for command blocks, but the newest prompt snapshot ends up without a rendered branch chip.

Logs / internal observations

From local investigation:

• warp.exe version: v0.2026.03.18.08.24.stable_01
• Example repo: E:\workcode\fofa-frontend-v5
• Example branch: feat/theme-light
• Warp local logs path: C:\Users\18339\AppData\Local\warp\Warp\data\logs\warp.log
• Warp local DB path: C:\Users\18339\AppData\Local\warp\Warp\data\warp.sqlite

If helpful, I can attach screenshots showing:

1. branch briefly visible during initialization
2. branch disappearing afterward, leaving only path/time chips
