Hi all used LTDC hardware inside the STM32f429 discovery board to drive a external 24 bit RGB display in 16 bit mode . full gui is designed in LVGL library , i was able to build it and flash it. i got the output on the display but with few issues .

1.the update speed of the gui elements are way too slow , so i cant update it real time

2.i am not getting a precised output some pixels are lost, 

3.can i change the horizontal animation happening when changing the screen

lvgl ver-8.3.11

i am using framebuffer method LVGL writes to framebuffer,

any help please
