Terminal Rendering Crash: Unhandled ENOBUFS Error During Large Content Paste

[DrMark]

Bug Description There is a display bug that crashes Claude. I have seen it happen a couple of times. Basically, the terminal (inside Windsurf) starts scrolling wildly and won't stop. Scrolling the mouse, home/end, dragging the window, etc. don't stop it. I think this is how to recreate: 1) have a large amount of history in the window, 2) have the system be thinking, 3) type a message in the window, then paste some content (like console logs to go with your message), 4) watch the system blow up. Sometimes, I have seen this happen when Claude is going to display one of the 1,2,3 choice dialogs. This is an urgent bug as this completely kills your history.
