Issues drawing in a Nokia 5110 LCD but only with Arduino Nano ESP32

Using Arduino Displays

Hi, I've been using this screen flawlessly with an old Arduino Nano (not ESP32) and a simulator (Proteus), using with my own simple code (using just drawBitmap) and using the Adafruit PCD5110 library example project, but when I tried to do the same with a new Arduino Nano ESP32 the code executed draws around twice as fast as in previous cases and 90% of the time with drawing mistakes (wrong pixels placement, showing Adafruit logo chopped in the middle, etc).

Could it be that the cpu frequency is too fast for the screen? I'm not sure how to handle that or if it's not even that what's causing it. Here are some examples, all in Arduino Nano ESP32, just pluging it and out 3 times:

Any advice regarding this?
Thanks!

You should show this, and the connections you use.

I think I found the fix for this: Putting "setCpuFrequencyMhz(100);" in Setup() made it slower and with 0 issues (for the moment). I tried with 20 and also works fine. Maybe this could help anyone with the same issue.
