Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This is a known issue with input lag in Agent Composer on the Glass layout. We’re already tracking it internally, but I can’t share an ETA for a fix yet. If I get an update, I’ll post it in the thread.

A couple quick questions to add more context to the report:

  • Does the lag start right after opening the Agents view, or only after you’ve been working for a while (lots of sessions, long chats)?
  • If you switch from Glass to the classic layout, does the lag go away?

That second one could be a good temporary workaround while we work on the fix.

hmm doesn’t Agents window = Glass layout? That’s where I’m seeing the lag.
No lag in classic layout from what I can tell

I see the lag even when I quit and restart the app

Yes, Agents window = Glass layout. Good to know the lag reproduces from a fresh start - useful data point.

This is still an issue in the latest build. Shouldn’t this be like a p0 issue? Really makes the product unusable
