Local branch picker: no feedback while git checkout runs (3–4s delay or more)

Branch picker in Local mode feels stuck for several seconds after selecting a branch

What I was doing

On the new task screen (Task Input), with Local mode and the posthog repo selected, I opened the branch dropdown and picked a different branch (e.g. from 39135 to master or another branch in the list).

What happened

• The dropdown closed right away
• The branch button kept showing the old branch name for about 3–4 seconds
• Nothing indicated that anything was happening — no spinner, no “switching…” text
• After a few seconds, the label finally updated to the branch I picked

It felt like the UI didn’t register my click, even though something was probably still running in the background.

What I expected

• The button should update immediately to the branch I selected, or
• Show clear feedback like “Switching to …” with a spinner while it’s working

Screen recording

(Disk was busy with other tasks too, so it took more time here.)

Environment

• PostHog Code (desktop)
• Workspace mode: Local
• Repo: posthog (large monorepo)

Additional context

In Local mode, changing the branch picker seems to run a real git checkout on the repo, which I guess can take a few seconds on a big codebase. That part is understandable — but the UI doesn’t show that anything is happening, so it feels broken until it finally updates.

Locate the Local-mode branch picker on the new task screen and trace the git checkout triggered when a branch is selected. Check how the branch label and loading state are handled; done means the selection gives immediate feedback until checkout finishes.
