1、The Terminal inside IDE is very slow while typing
2、The process “Cursor Helper (Renderer)” takes high CPU usage while using Cursor so that the IDE is very slow
Steps to Reproduce
run the IDE, use the terminal
Operating System
MacOS
Current Cursor Version (Menu → About Cursor → Copy)
Hey, thanks for the report. For performance issues like this, let’s run some quick diagnostics:
Quick checks:
Run cursor --disable-extensions in your terminal. Does the slowness still persist?
Open Activity Monitor, sort by CPU, and share a screenshot of all Cursor processes
Enable Extension Monitor: Settings > Application > Experimental > Extension Monitor Enabled, then press CMD+Shift+P and run “Developer: Open Extension Monitor”
It would also be helpful to know:
What’s your exact macOS version? (Apple menu > About This Mac)
Does the slowness start right away, or only after using Cursor for a while?
Have you installed any extensions recently?
Which shell are you using in the terminal (bash, zsh, fish)?
This will help us understand if the issue is related to extensions, a nightly build regression, or something else. Let me know what you’re able to collect.
