Latest build forces layout change when you run a task

[TomFrankly (Thomas Frank)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I updated Cursor this morning on my MacOS machine. Now, whenever I run my configured user task (I have one that runs a build for our browser extension), the Cursor app interface moves all the panes.

I prefer the agent column on the left, then the editor, then the file browser on the far right. Running a task flips this order.

This happens whether I use a configured key binding or run the task directly from the action bar (⌘+Shift+P).

Steps to Reproduce

Running a user task.

Expected Behavior

In the past, the UI would not change in any way as a response to running the task.

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report!

This is an interesting one. I haven’t seen running tasks directly cause layout changes before.

A couple of quick questions to help us investigate:

1. Which layout mode are you using? (Agent Layout, Editor Layout, or a saved Custom Layout?)
2. Did you save your custom panel layout using the layout settings gear icon in the top-right corner?
3. Does the issue still happen after you restart Cursor after saving the layout?

Also, could you check if there’s a keyboard shortcut conflict? Sometimes task runners can trigger shortcuts that affect the sidebar. Go to Settings > Keyboard Shortcuts and look for bindings related to your task.
