I have similar problems with a display that uses the KS0724 or the S6B0724. I have displays going off, contrast setting changing randomly, even configuration bits change, setting the display into reverse mode. My displays are on network nodes that are powered by the network in a very EMC hostile environment so I suspect EMC problems. The boards are 4 layer with ground and power planes, decoupling is sufficient and still the problems occur. In my case it was allowed to make a screen saver function that holds the display in reset and re-initialises when a button is pressed. Rather brute-force but the only way of getting it right. Even reconfiguring the display on regular intervals did not help, a real reset was necessary.
