VS Code extension repeatedly spawns git rev-parse --show-toplevel in multi-repository workspace when Codex panel is active #33165

What version of the Codex App are you using (From “About Codex” dialog)?

What platform is your computer?

Windows 11 (10.0.26200)

What issue are you seeing?

When the Codex panel is activated in a workspace containing several nested Git repositories, git.exe is spawned continuously running:

git -c core.hooksPath=NUL -c core.fsmonitor= rev-parse --show-toplevel

CPU usage rises noticeably. Closing VS Code immediately stops the Git processes.

Codex hidden → no repeated Git processes.
Click Codex tab → repeated git rev-parse --show-toplevel.
Git Output channel does not show these commands.
Process Explorer shows the Git processes are children of the VS Code process.
Switching to a folder containing only one Git repository causes the Git loop to stop and CPU returns to normal.
