Actually I think it may have something to do with my use of the Wire.h 
class...When I get a receiveEvent screen is affected

That would make more sense. This library requires exact timing meaning no other 
interrupts my be used with it. The wire library uses interrupts. I would 
suggest trying the modified i2c library used by the video game shield.

Ensure there are no other interrupts running.
