Bug report: 30–60s agent response delay after commands (inference latency)
Product: Cursor IDE
Area: AI Agent / “Run command” workflow
Model: Sonnet 4.5, Composer 1, GPT-5.2, actually all of them
OS: Windows 10.0.26200
Shell: PowerShell (integrated terminal)
Workspace: on a windows dev drive (git repo)
Summary
After running terminal commands via Cursor’s AI Agent, the command finishes quickly but the agent UI remains in “Generating…” for ~30–60 seconds before responding. This delay appears to be LLM inference/response generation time (or queueing/time-to-first-token), not command execution or output processing.
Expected behavior
Agent should respond within a few seconds after command completion for trivial commands (e.g., echo ok), especially when terminal output/context is small.
yes. Cursor has been using the git bash terminal without issues until the upgrade to the new terminal system (or whatever prompted the need for a use Legacy Terminal setting), and then if I used the legacy terminal option it continued to work. Since the last update, maybe 2, even the legacy terminal keeps crashing.
I’m not sure how legit this is, but this issue with the terminal crashing seems to happen more often when commands output includes non-standard characters like emojis or colors. I’ve also noticed an increased occurrence when the agent tries to concatenate commands like
This issue, along with the enormous expense of Cursor, pushed me to use Google Antigravity. Antigravity is massively cheaper and faster and better in every way really except for MCP support. Their mcp server support is buggy. Their terminal works way, way better. I trust it to do search and replace across multiple files simultaneously and edit multiple files in parallel. When it messes up, which is rare, it easily and quickly fixes it the majority of the time without me reverting. It is soooo much faster and more reliable. I also really like the memory system. It creates planning documents, tasks lists, and walkthroughs and indexes them for between thread recall. The mian thing is Cursor is just too expensive. It’s insane.
Unbelievable. Not only did Cursor agent stop working, it logged me out of everything, and now won’t open any folders. Completely unusable. Guys… what is going on?
Also, lol, I can’t even make a new topic in this forum.
I didn’t see any mention of the terminal in the latest changelog but it seems to be a hell of lot more stable today. I’ve had zero terminal crashes this morning while working on two separate projects. So kudos to you guys for fixing this (if it actually was fixed and I’m not just getting lucky lol)
