This continues to be problematic, and is massively affecting my multi-agent workflow, causing massive load spikes on my debian 32gb 5600 server (>100) if I happen to keep several agents in tmux windows, not even active, but if I happen to switch to them, or reconnect to my tmux session (as indicated, almost anything will cause it to re-emit thousands of lines of scroll buffer) - it is THIS that brings my server to its knees. I have to then just twiddle my thumbs for the 5-45m of time until the server’s load processes its backlog and becomes interactive again.
Again, to be clear, Claude and codex do not suffer from this. Only cursor.
I now have to actively kill agents when not in use, to avoid cursors scrollback penalizing my workflow.
