Why is the display of my button control using TouchGFX not clear?

[zhaowhong]

Hi

My project is using an alientek 4.3 inch TFTLCD screen, which is driven by FMC (Flexible Memory Controller).
And  ，The display effect of the button control does not meet my expectations after I load it.“next text”is my button,

that there are many horizontal dots or speckles inside。

thank you

That would be very appreciated! :smiling_face_with_smiling_eyes:
