I have temperature related failures of LCDs. On a hot day and after
running for a while the LCD stops working correctly, the same code
works well with other brands of LCDs, don't know what chip it uses,
just 2 blobs.
I have heard of people putting small caps (15pf or so) in the E line,
don't know if this will help with your problem or mine.
