Hey, thanks for the report. This is a serious issue, so let’s try to narrow down the cause.

Could you please check the following:

  1. Start Cursor from the command line with extensions disabled: cursor --disable-extensions Does the issue still reproduce?

  2. Open Process Explorer (Ctrl+Shift+P → “Developer: Open Process Explorer”) before Cursor freezes. Which process is using the most CPU/memory?

  3. Enable Extension Monitor (Settings > Application > Experimental > Extension Monitor Enabled), then open it (Ctrl+Shift+P → “Developer: Open Extension Monitor”). Which extensions show high activity?

  4. Check the Developer Tools console (Help > Toggle Developer Tools). Do you see any red errors right before the freeze?

Also, I found a possibly related issue on Ubuntu 24.10+, but you’re on Ubuntu 24.04, right?

This info will help us tell whether it’s extensions, performance, or something Ubuntu-specific.

  1. i will check and let you know. this is how i will run cursor : /programs/Cursor-2.1.36-x86_64.AppImage --no-sandbox --disable-extensions &
  2. According to TOP the cursor process uses 100% of the CPU when it freezes
  3. lsb_release -a

  1. indeed removing some of the extensions helped, and it happens less frequently.
  2. However, cursor is still getting into a mode of 100% CPU usage and freezes.
  3. It seems related to other applications (docker) running at the same time
