### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug For some reason Cursor is reliably crashing every single time I make an edit to a file in Agent mode. To test this I: - Created a new folder with no files - Cleared chat history - opened with all extensions disabled Yet still, basically the UI freezes the moment that it goes to edit a file (the planning UI still works well). This renders agent mode ENTIRELY unusable for me, I’m a bit disappointed by this ### Steps to Reproduce - Created a new folder with no files - Cleared chat history - opened with all extensions disabled - Tell it to create an index.ts file in that empty folder ### Expected Behavior It creates a file and doesn’t freeze ### Operating System MacOS ### Current Cursor Version (Menu → About Cursor → Copy) Version: 2.0.43 VSCode Version: 1.99.3 Commit: 8e4da76ad196925accaa169efcae28c45454cce0 Date: 2025-10-30T18:49:27.589Z (3 days ago) Electron: 34.5.8 Chromium: 132.0.6834.210 Node.js: 20.19.1 V8: 13.2.152.41-electron.0 OS: Darwin arm64 25.0.0 ### For AI issues: which model did you use? Tried multiple models happens with all ### Does this stop you from using Cursor Yes - Cursor is unusable ---

Hey, thanks for the report. This is a known bug in v2.0.43. Several users fixed the freezes/memory leaks by changing one setting. Try this: - Open Command Palette `Cmd+Shift+P` → Preferences: Open User Settings (JSON) - Find `"workbench.editor.showTabs": "single”` - Change it to `”multiple"` or remove the line - Restart Cursor This setting is causing Agents layout freezes and memory leaks in the current version. ---

Thanks this fixed the issue for me on v2.0.64 I like single tab view - will this be fixed soon? ---

This temporary solution worked on v2.1.34 as well, but is there any timeline for fixing this issue? I also prefer the single tab view ---
