I really love Claude Code but it's wild to me if others aren't seeing this. Is Ctrl+R usable at all? I've given up on it, the whole screen just starts scrolling madly most of the time. Not that I have to press Ctrl+R to get that bug to happen, it's just the most reliable way to do so. And I've had the input box stuck not accepting input or not allowing me to delete past a certain point a hundred times. By now I know how to get it unstuck (although I couldn't tell you - my fingers figured it out but my brain doesn't know).
