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.
