Strange things….

To follow up….
12Megs Xtal LCD is fine.
8Megs Internal Clock… Garbaged LCD.
Lowered to 4Megs Internal Clock LCD all fine

Had a look at control lines for LCD with scope….. All fine and square with Xtal, Not so with 8Megs Internal Clock

Lowered to 4Megs Internal clock, Control lines OK again.

Running of a battery so not line pickup….Lots of 0.1uf caps close to key IC's.

Interesting though…. ??
