@deanrie could you take a look when you have time?

Hey, thanks for the report. This is a known terminal rendering issue. Cursor’s gpu-process uses noticeably more GPU than VSCode when the terminal is actively updating. A few users have reported this, especially on Windows + WSL.

Try this workaround. It helped other users with the same issue:

1. Ctrl+Shift+P → “Preferences: Configure Runtime Arguments”
2. In the argv.json file that opens, uncomment (or add) this line:

   "disable-hardware-acceleration": true
   

3. Fully close all Cursor windows, then reopen Cursor

Also, please share a few things so we can dig deeper:

• Ctrl+Shift+P → “Developer: Open Process Explorer” and send a screenshot when GPU usage peaks
• How many terminals do you have open when this happens?
• What are your monitor resolution and refresh rate?

This should noticeably reduce GPU usage. Let me know how it goes.
