Glitches while using two frame buffer

  • I am using Qt MCUs 1.3.0 for STM32f769i disco board.
    in that i am getting so much of glitches in the screen while using two frame buffer .but while using single frame i am getting glitches only in screen change.
    my frame buffer size is ( LCD_WidthLCD_height32)/8 .
    LCD_freq is 30Mhz.
    Is anything else i needs to config in LTDC?
