Silly questions:
1. What happen if you remove ALL ferrite beads?
2. what happen if you leave all unused i/o to input when you do ADC reading instead of setting them to LOW or HIGH
3. do you have any 10uF-47uF tantalum capacitor close to the GLCD Vdd rails
4. What happen if you use lower voltage for ADC convertion.
5. what happen if you tie VEE to GND with a 10k resistor
6. what happen if you load WAIT pin to GND or VDD with a resistor?
7. What happen if you slow down the ADCs readings?
8. How far the GLCD is away of the PIC?
9. What happen if you use some resistor in serie to the adc pins + 0.1 uF to GND?

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
