Cursor IDE
Describe the Bug
During my subagent adventure this morning (Better subagent control in the Cursor IDE), I had great difficulty entering commands into the agent window, since my local machine was under a heavy CPU and memory load. Text entry into the agent window should be async or privileged so that it’s always able to accept user inputs.
Steps to Reproduce
- Place machine running IDE / cursor processes under load (e.g. by spawning many subagents)
- Attempt to enter text into agent text entry buffer
Expected Behavior
Text entry should be viable and prioritized at all times so the user can always issue commands to agents. However, in this case, I had to resort to writing a command in a text editor and pasting it in, since my keystrokes were only being picked up sporadically.
