What issue are you seeing?

During normal Codex App task execution on Windows, a git.exe command-line window repeatedly flashes/pops up. The window appears almost instantly and disappears too quickly to read the full command; only git.exe is visible.

This started recently. Rebooting Windows multiple times and restarting Codex does not resolve it.

Based on local inspection, git.exe is the normal Git for Windows console executable. The visible popup looks consistent with Codex launching Git from the desktop GUI context without hiding the console window.

Why this seems app-side

• The behavior happens while using Codex App tasks, not from a user-initiated terminal command.
• Restarting Windows and reopening Codex does not fix it.
• Git itself works normally from PowerShell.
• The symptoms resemble earlier Windows app reports where Codex repeatedly spawned Git and conhost processes.

Related prior issues that look similar:

• #17229: Codex Windows App repeatedly spawning git.exe status --porcelain=v1 -z and conhost.exe
• #20933: Windows desktop app triggering multiple git.exe add -A / rev-parse processes when opening a project/chat
• #20867: Windows desktop app update causing unresponsiveness and repeated Git metadata work

Expected behavior

Codex should be able to run Git status/snapshot commands on Windows without showing transient git.exe / console windows to the user. If Git is launched from the desktop app, it should use a hidden/no-window process creation mode.

Actual behavior

A git.exe console window repeatedly flashes during Codex task execution.

Additional notes

I considered a local workaround using a Git wrapper, but this should ideally be fixed in the app by launching Git with the appropriate Windows no-console/no-window flags rather than requiring users to replace or wrap Git.
