There are two main reasons; if the LCD display drive voltage is low or the divided-voltage is variable, then it is not possible to drive the display correctly.
If the selected frame frequency is very fast, the LCD display may not be driven correctly due to a lack of driven capability.
Therefore, please adjust the driven-voltage and the value of frame frequency, taking into account the LCD panel performance.
