[Junde]

Hi there,

I am using TouchGFX with STM32F429BI. 

Everything is work well expect when the UI screen is chenging.(MCU CLK = 168MHz, and display is 800*480, and I have some other demo the screen change is work well.)

When the screen is chenged, the display will splash maybe 100ms, then the new screen present normally.

I have no idea why this happend and how to resolve it?

Coulu someone give me some advices?

Thanks
