display.refresh()Behavior
My hardware is ESP32-S2-MINI-2-N4R2 module.
The image does not refresh.
But if I modify the main loop to the following one, It works.

display.refresh()Also, another small issue. I have external pull down resistor on the IO45. But when the circuitpython is running, the IO45 is still HIGH. That why I have to use digitalio to set it to LOW. But I have no idea about the reason.
