Environment Details 
- Cursor IDE Version: 0.46.4
- Operating System: Windows
- Issue First Observed: February 19, 2025, following upgrade to version 0.46
- Affected File Types: Exclusively
.mdc
files - Scope: Occurs in all projects
Bug Description 
When editing any .mdc
file in Cursor IDE, the editor automatically saves the file mid-typing and scrolls the view to the top of the document. This behavior occurs during active typing sessions without any specific triggering actions or keyboard combinations. The unwanted auto-save and scrolling interrupt the editing workflow and make it difficult to maintain focus on the current editing position.
Reproduction Steps 
- Open any
.mdc
file in Cursor IDE v0.46.4 - Begin typing content into the file
- Observe that while actively typing, the editor will:
- Automatically save the file (without explicit save command)
- Scroll the view to the top of the document
Screen recording 
Troubleshooting Attempted
- Disabled nearly all extensions
- Restarted the IDE
- The issue persists despite these measures
Impact 
This bug significantly impairs productivity when working with .mdc
files, as it:
- Disrupts the editing flow by unexpectedly changing the view position
- Forces constant repositioning to the previous editing location
- Makes sustained editing of
.mdc
files impractical
