Text mirrored and cursor jumps to start in detached agent windows

[SMartin]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The text gets mirrored when I type in an agent tab that’s in its own window. For example, ‘Hello’ becomes ‘olleH’. I’ve found a manual fix: if I type the first letter and then click right after it, it starts working correctly. It seems like the cursor automatically jumps back to the start of the text box when I type directly.

Steps to Reproduce

Open the IDE and create a new agent. Drag the tab outside the editor to open it in its own window. Click out of the agent’s text box, then try clicking back in.

Additional Information

The text box behavior is also glitchy when deleting letters; it often snaps back to the beginning of the line or the first character.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, this is a known issue. Text can type backwards in detached Agent windows because of multi-window rendering limits.

Workaround: after you open Agent in a separate window, press Ctrl+Shift+P, type Developer: Reload Window, then press Enter. This should temporarily fix typing. You might need to do it again if the bug comes back.

Another option is to avoid using a separate window and set window.zoomLevel in settings.json if you need a different zoom level.

The team is aware of this issue. There’s no ETA for a fix yet, but every report helps us prioritize it. More details and discussion here: Editor in a new window, zoomed in, typing from right to left.
