Blank Cursor Window

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Main cursor window is blank, with only the previous window layout being shown.
Opening a secondary cursor window works just fine, but doesn’t override the configuration of the main one.
My theory is that a bugged “Open Chat as Editor” window is trying to load each time, causing the load to fail.

Steps to Reproduce

Started a plan, top right of chat > “Open Chat as Editor”
Chat window should go blank, and an error should pop up on the bottom left “e.setData is not a function”
The IDE should behave normally UNTIL you attempt to restart it.

Expected Behavior

Chat should open as an editor window.

I tried, among other things;

  • Reset VSCode window restoring settings - No Effect.
  • Cursor Max Tabs set to 1 - Had effect on main (broken) window but froze and crashed.

The Fix;

  1. Navigate to
  • Windows: %APPDATA%\Code\User\workspaceStorage\
  • macOS: ~/Library/Application Support/Code/User/workspaceStorage/
  • Linux: ~/.config/Code/User/workspaceStorage/
  1. Find the affected workspace, delete state.vscdb and the backup file.

Caveat is that editor window & chat sessions may be lost.
