Support Bug Reports

Hi,

Same issue!!

I downgraded to 3.9 and it is working now.

33

Well, it still hasn’t shipped in 3.11.13 which I just updated to after previously downgrading to 3.9. I upgraded because you said it should’ve been in ~3.10.20…

It’s still not fixed. Is this deliberate?

Hey there.

We can’t reproduce this and a few users have reported that it’s fixed in newer versions. Providing more details would be helpful!

Here is my experience on 3.11.13.

  1. Codex no longer shows in the list of my extensions as it used to in the left side bar (like when clicking the chevron in the top icon nav section). I had it pinned so it should always be visible.
  2. Doing Ctrl+Shift+P and Codex:New Codex Agent first opens a new tab then briefly shows the codex logo while it load and then just a blank tab with the title “new”.
  3. In the tab section in the center, if i click the three dots on one of the tabs and click Open Codex Sidebar, Codex now shows in the Cursor Agent sidebar in the right hand side vs being in the left side bar with the extensions. This forces me to constantly toggle open and close the codex and cursor agent windows if i want to use them in parallel.

I experienced a similar issue in Cursor.

The Codex icon disappeared from the Primary Side Bar, even though it had previously been pinned there.

I also had Cmd+Shift+C assigned to Focus on Codex View, but the shortcut stopped working.

When I manually ran Open Codex Sidebar, Codex opened inside the Agent sidebar on the right instead of returning to its own view in the Primary Side Bar on the left.

I then tried dragging the Codex view back to the left. The behavior was very inconsistent: on most attempts, Cursor placed Codex as a nested section inside another view such as Explorer, instead of restoring it as a standalone sidebar view. After around 15 attempts, it finally returned to the correct location.

However, the original shortcut was still broken. The keyboard shortcut debug logs indicated that Focus on Codex View failed because the Codex view had not been initialized or opened yet, so there was nothing to focus.

My workaround was to reassign Cmd+Shift+C from Focus on Codex View to Open Codex Sidebar. The shortcut now works again.

So there seem to be two related issues:

  1. Codex randomly disappears or loses its location in the Primary Side Bar.
  2. Focus on Codex View cannot reopen or initialize the view once it is missing.

Thanks for you fantastic work btw
