Hey, thanks for the report. The Renderer process in Cursor (Electron/Chromium) hits a hard hardware limit of about 4 GB of memory, then crashes with this OOM code. This does not depend on the total amount of RAM in your system.
I can see you have already tried a lot (reinstall, GPU acceleration, extensions, Early Access). Here is what else is worth checking:
-
OTEL memory leak check:
Ctrl+Shift+P>Developer: Toggle Developer Tools> Console. Look for lines with[otel.error]orOTLPExporterError. If you see them, that is an additional memory leak on top of the main limit. -
Workarounds that actually help:
- Rotate chats. Start a new chat when the current one gets big, especially before long agent workflows.
- Monitor memory:
Ctrl+Shift+P>Developer: Open Process Explorer. - If it is already crashing on startup, delete recent chats via Chat History.
More discussion and context here: Cursor crashes repeatedly with out-of-memory (OOM) errors after the latest update, especially during large prompts or long-running plans
Let me know if you see any OTEL errors in the Console, and if rotating chats helps.
