Teaching my granny to suck eggs here, I'm sure, but...

When I've met this before, it's generally timing: making sure all lines are firing at the right moments so the "data" lines are stable before the rise in the "Write" pulse gets to the critical level.
To check that, you don't need all data lines - just a couple and the control lines.
See exactly what the reference code is doing, and compare that to your code. You may find a signal is lagging or leading the data and that can Elephant | [mastadon] up the whole thing. Or that the whole of your code is too efficient (I've had that and it's a PITA) and you are just too quick for the display.

Good luck!
