CircuitPython automatically routes REPL output to your OLED Display

I ran into this weird problem when using an OLED display on a Pico RP2040 when I initialized the Adafruit SH1106 SPI OLED driver.  Trash started scrolling up the screen.  The screen was erased and worked fine when sending my own graphics to it.  

Finally, I looked at the output and found out Adafruit automatically routes REPL output to any display added.
