Cursor Preview Mode Bug

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I open a markdown file, it opens a preview in the right pane. All works well so far. Now, if I open another file, like a Python file, it will still open a preview tab for it and crash the IDE.

Steps to Reproduce

  1. Open a .md file and wait for the preview tab to open up
  2. Open any other kind of file and observe how new preview tabs open up

Additional Information

This bug doesn’t happen in VS Code

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is quite strange behavior. Could you check if you have any extensions installed for automatically opening file previews, like Auto-Open Markdown Preview?

I forgot I had this extension and thought that it was a default VS Code feature. Uninstalling it fixed it, thanks
