Where does the bug appear (feature/product)? Cursor IDE Describe the Bug I’m using the latest version of Cursor on Windows 11, and it’s using up a significant amount of my GPU, causing my computer to overheat and experience interface lag. I’ve tried switching the GPU Cursor uses, but Cursor always …

Hey, thanks for the report. This looks similar to a GPU issue we’ve seen. To help diagnose it, please share: Process Explorer screenshot: Ctrl+Shift+P → “Developer: Open Process Explorer” Actual GPU usage (%) from Task Manager while Cursor is running A test with extensions disabled: launch Cursor…

The issue is caused by the AI pane, and is evident when a very long conversation thread is being worked on in Agent mode. If i close the AI pane, or switch to a new conv…

I also confirm that the GPU usage is related to the terminal. And especialy when it scrolls. It’s a big concern when runing auto reload servers and having huge stack trace. It seems to eat a lot even on high end GPU, looks like there’s a loop on the refresh that copies same memory many times. I a…

I finally found the cause and created an issue on xterm, please upvote and share it : https://github.com/xtermjs/xterm.js/issues/5447 You’ll see what’s the problem and how to solve it.
