I get this on mac, irrespective of whether claude is running in VS Code integrated terminal, or iTerm2, the same output is in the window 5 or 6 times.

same here, when I scroll UP I can see multiple times The creation of the same table with the code repeating itself

I found it producing no duplications/mess in full-screen mode (/tui fullscreen). This mode is actually more convenient. Found it randomly.
