Hi my display stays blank when using the Pro Mega 2500 and Adafruit GFX 1.10.0

Any recommendations as to how to debug? Maybe some DEFINE I can set for debug messages?

Hi and thank you for using my lib.

first double check the wiring, also note that only hardware SPI is supported, and the display's chip select "CS" pin must be connected to PORTB on AVR

from readme:

lib is tested with old Adafruit GFX 1.1.5, may work up to 1.2.2, newer versions are not tested

..in other words, i dont like the new versions of GFX as it breaks most of stuff i have done over the years and its code became mess..

i will help you to make it work
can you post photo or describe wiring? something like pin 8 -> display cs
