Every update seems to make Cursor IDE worse. Please stop and test

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Guys, are you testing the IDE? Every update makes it worse.

When I reference .vue files - IT LITERALLY STARTS TYPING BACKWARDS AND CRASHES.

When I type “config:” - IT FREEZES UP AND CRASHES.

Now every time I start Cursir, it FREEZES UP.

I tried deleting my .cursor in my home directory.

What are you doing?

Steps to Reproduce

Accept the updates to the current version.

Operating System

Linux

Current Cursor Version (Menu → About Cursor → Copy)

It crashed. THe current version. I accepted the update.

Does this stop you from using Cursor

Yes - Cursor is unusable

Michael_Cole · November 9, 2025, 7:34pm

Open Cursor
Open the AI Pane
Right-click a Chat → Open as Editor
Drag and drop file onto prompt
It goes screwball:
Internal Lexical error: invariant9() is meanto to be replaced ad compile time. There is no runtime version. Error: Reconcilliation: could not find DOM element for node key %s.
starts typeing backwards
Crashes and needs to be restarted.

Open as Editor may be the problem.

I have 4 monitors. I don’t want an AI sidebar. I want an AI window.

This seems like one of several bugs.

Hey, thanks for the report. The console errors point to a multi‑window rendering issue, likely triggered by your “Open as Editor” + 4‑monitor setup. Let’s troubleshoot:

First, test with extensions disabled:

Close Cursor
Run from terminal: cursor --disable-extensions
Try your workflow - does the issue still happen?

Check your settings:

Open Command Palette Ctrl+Shift+P → Preferences: Open User Settings (JSON)
Look for "workbench.editor.showTabs": "single" - if present, change to "multiple"
This fixed similar Agent tab freezes: Toggling the new switch to "Agents" freezes the app

Also need:

Exact Cursor version: Help > About Cursor > Copy
List of installed extensions (if relevant)

Note: Your console shows an MCP server path error /home/michael/code/wikiagent/etc/mcp-d3/.venv/bin/mcp-d3-server ENOENT - the missing MCP server could add instability.

Let me know what you find.
