Hello, I'm using a SPI TFT Display 128x160 Pixel with a RPi3B+ and for the momento I've used the examples python scripts. Now I moved to a RPi4B. First time I wired and configured everything worked as expected, but now I'm experiencing only a white screen. If I go back to the RPi3B+ the display still works, and I'm sure it works on the RPi4 because I have a video output if I use a adafruit library. On both Pis I have a fresh installation of Raspbian OS Lite 64 bit

This is the Kernel version of the RPi4B Linux raspberrypi 6.1.19-v8+ #1637 SMP PREEMPT Tue Mar 14 11:11:47 GMT 2023 aarch64 GNU/Linux

I have the same display running on a Raspberry Pi 4 with no problems.
